The short answer
Malta is an island country in the central Mediterranean, south of Sicily, east of Tunisia and north of Libya: 316 square kilometres and about 588,000 people, on three inhabited islands, Malta, Gozo and Comino. It holds three UNESCO World Heritage Sites: the Megalithic Temples of Malta, built in the Neolithic and among them Ġgantija on Gozo and Ħaġar Qim and Mnajdra on the main island’s south coast; the Ħal Saflieni Hypogeum, an underground burial complex cut into the rock; and the City of Valletta, the capital the Knights of St John began in 1566. The islands are also crossed by cart ruts: pairs of parallel grooves worn or cut into the bare limestone. The densest cluster is at Misraħ Għar il-Kbir, near the Dingli Cliffs in the south-west, and what made them, and when, is one of the most argued-over problems in Maltese archaeology.
From Tally’s diary
Bare pale rock near high cliffs, wild thyme in the cracks, a hot wind, and the sea very blue and a long way down. The ground was scored with pairs of grooves running side by side, crossing, forking, heading for the edge as if the traffic had kept going. Church domes on every skyline. I stood at the junction and waited, politely, for something to come.
Why it's worth knowing
Most of what this page covers is made of the same material. The islands are limestone, and the places on this page were stacked from it, dug into it or worn into it: temple walls raised in the Neolithic; burial chambers cut three levels down at Ħal Saflieni; a fortress city built on the bare rock of the Sceberras peninsula after 1565; and, on the open ground near the Dingli Cliffs, pairs of grooves crossing one another like the lines outside a railway station.
Some of the stones still keep time. At Mnajdra, on the south coast, Heritage Malta notes that the doorway of the South structure is aligned with the sunrise at the spring and autumn equinoxes, and that at the winter and summer solstices the rising sun’s beams pass along the sides of the main doorway, each time lighting a different decorated slab inside the first chamber. What the builders meant by it is a separate question; the alignment itself is in the stones.
The plainest marks are the least understood.The University of Malta, summarising cart-rut research, gives the predominant view as prehistoric, somewhere between 5200 and 750 BC; other estimates run as late as the Middle Ages, and nothing yet dates a rut directly. Ruts are recorded on the shore of St George’s Bay at Birżebbuġa, on the south-east coast, and a University of Malta study notes a pair that enters the sea and carries on some distance under the water.
The field notes
The temples, older than the questions
Malta’s megalithic temples were built between about 3600 and 2500 BC, by the range Wikipedia’s article on them gives, and until the discovery of Göbekli Tepe in Turkey they were claimed as the oldest free-standing structures on Earth. Heritage Malta’s own page for Ġgantija gives a wider span for that site’s two structures, 3800 to 2000 BC. UNESCO inscribed Ġgantija on Gozo in 1980 and added Ħaġar Qim, Mnajdra, Ta’ Ħaġrat, Skorba and Tarxien in 1992.

Ġgantija stands on the Xagħra plateau on Gozo: two structures with separate entrances, enclosed in one outer megalithic wall, each a set of apses off a central corridor. Heritage Malta notes that its builders used the hard-wearing Coralline limestone extensively and kept the softer Globigerina for inner furnishings such as doorways, altars and decorated slabs, and that two fragments of plaster with red ochre suggest the inner walls were once plastered and painted.
Ħaġar Qim sits on the crest of a ridge above the open sea. Its doorways are either trilithons, two uprights with a lintel, or “porthole” openings cut through a single block, and parts of it were roofed by courses of megaliths, each smaller than the one below. Mnajdra lies about 500 metres downhill, and Heritage Malta reads the closeness as a sign that one community likely used both. The two have stood under protective shelters since 2008, put up to slow the deterioration Heritage Malta has watched since they were excavated.
At Ħal Tarxien, found by the farmer Lorenzo Despott in 1913, a complex of four structures, the South structure carries relief carvings of spirals and of animals, among them goats, bulls, pigs and a ram, beside the lower part of a colossal statue of a figure in a pleated skirt. The temple-building culture disappeared around 2500 BC. In the Early Bronze Age newcomers turned parts of Tarxien into a cremation cemetery, and a later Bronze Age phase, Borġ in-Nadur, from about 1500 to 700 BC, is named after a site in Birżebbuġa, the same town as the St George’s Bay ruts.
The Hypogeum, dug downward
The Ħal Saflieni Hypogeum, on a hilltop in Paola not far from the Grand Harbour, is the temple culture turned inward: halls, chambers and passages hewn out of the Globigerina limestone, in use from 4000 to 1500 BC by Heritage Malta’s dating. It was dug in three levels, its users going deeper as space ran short. Some smoothly finished chambers on the middle level recall the interiors of the temples above ground; the deepest room, on the lower level, lies 10.6 metres below the road.
It was found by accident in 1902, by a stonemason laying foundations for a row of houses. Most of the houses were finished before the find was reported, and the upper level was damaged beyond repair; the site became public property at the end of 1903 and was excavated until 1911. Its finds include pottery, human bones, ornaments, small carved animals and the figurine known as the Sleeping Lady, now in the National Museum of Archaeology in Valletta. UNESCO lists the Hypogeum as a World Heritage Site; Heritage Malta’s page dates the listing to 1981, while Wikipedia, citing UNESCO, gives 1980, the year Ġgantija was inscribed.
Heritage Malta lets 10 people into the Hypogeum at a time, and gives preservation as the reason: carbon dioxide, temperature and humidity in the chambers all change with the number of people inside.
Valletta, the city on the ridge
In 1565 an Ottoman force besieged Malta, then held by the Order of St John. Fort St Elmo, at the tip of the Sceberras peninsula, took the brunt of it; by Heritage Malta’s account the small fort held out for a month and surrendered on 23 June. The siege as a whole ran from 18 May to 8 September 1565, by the dates in Wikipedia’s account, and ended with the island still in the Order’s hands.
Valletta was begun the next year on that peninsula, which the Malta Tourism Authority describes as arid rock rising steeply between two deep harbours, Marsamxett and the Grand Harbour. The city is named after its founder, Grand Master Jean Parisot de la Valette, and the Tourism Authority says its bastions, forts and cathedral were completed in 15 years. UNESCO inscribed the City of Valletta as a World Heritage Site in 1980, by Wikipedia’s account citing the World Heritage List.
The threads of this page meet inside it. The National Museum of Archaeology occupies the Auberge de Provence, a Knights’ building dating to 1571, and holds the Sleeping Lady from the Hypogeum, the figure known as the Venus of Malta and the colossal statue from Tarxien. Fort St Elmo, brought inside Valletta’s fortifications in 1689, took the first aerial bombardment of the islands on 11 June 1940 and now houses the National War Museum, which shows Malta’s George Cross.
Tracks in the rock
A cart rut looks like a question with an obvious answer. Two grooves, a steady distance apart, running across a hillside: something with wheels went this way, many times, until the rock gave in.
The trouble starts when you try to finish the sentence. A typical Maltese rut is 10 to 35 centimetres deep, with 100 to 130 centimetres between the inside edges of a pair. At Misraħ Għar il-Kbir, in the limits of Siġġiewi near the Dingli Cliffs, pairs cross others or join them at junctions, which is why the site is known in English as Clapham Junction, after the busy London railway station; Wikipedia credits the nickname to the archaeologist David Trump, who wrote a book on the ruts in 2008. Whatever made the pair that runs on under the sea did so on ground that was dry at the time; the sea is higher now, or the land lower, and the tracks carry on underneath.
Carts, soft rock and rain
The most developed explanation is geomorphological. In 2008 Derek Mottershead, Alastair Pearson and Martin Schaefer, in the journal Antiquity, modelled the ruts as the product of two-wheeled carts with a gauge of about 1.40 metres carrying moderate loads. In wet weather, when the soft limestone is weakest, the wheels would cut into it progressively.

Their model also explains the junctions. As a pair of ruts deepened, the cart’s body would eventually scrape the rock between them, at a ground clearance they put at about 0.675 metres, and the driver would move over a few centimetres and begin wearing a new pair. A rut network, on this reading, is a record of traffic repeatedly abandoning worn-out lanes.
How alike they are
In a study published in 2022 in the Journal of Archaeological Science: Reports, Huw Groucutt measured the variability of the ruts. The typical Maltese rut is about 15 to 30 centimetres wide at the top, narrowing to 5 to 15 at the base, and 10 to 35 centimetres deep, with typically 100 to 130 centimetres between the inside edges of a pair.
Groucutt concluded that the ruts are fairly standardised, which may suggest a consistent age and function, and noted that what standardisation means in this setting is not clear. That is the state of the question: the measurements narrow the range of answers without choosing one.
Where to see them
Misraħ Għar il-Kbir lies in the limits of Siġġiewi, near the Dingli Cliffs and the Buskett woodland, on open, uneven rock. Ruts are also recorded at Busewdien, Naxxar, San Ġwann and Bidnija, and on Gozo. The Birżebbuġa ruts are on the shore of St George’s Bay in the south-east, near the remains at Borġ in-Nadur and the cave of Għar Dalam.

- Go early, before the rock gets hot, and take water.
- Keep to the bare rock. The fields around it are farmed and planted, and the farmers would like them left that way.
- Stand where the grooves cross, pick one pair, and follow it as far as it goes.
- Find the pair that walks into the sea, and do not ask it to explain itself.
- Decide what made them, then decide again on the walk back. The list is keeping every answer, in case the ruts ever say.
A relic from Malta
Relic, entry 85Recorded: St George’s Bay, Birżebbuġa
The ruts that walk into the sea. Somewhere on Malta’s coast a pair of cart ruts runs down the rock and carries on under the water, and ruts are recorded at St George’s Bay in Birżebbuġa. Whatever made them made them on dry ground; the sea has risen, or the land has sunk, since. They are two grooves in the limestone, a steady distance apart, and they give no sign of having noticed.
Tally, in the marginTwo grooves in the rock, walking calmly down the shore and into the sea. I stood at the water’s edge for some time, waiting to see whether they would come back out.
Getting there
- 1
Arriving on the islands
Fly into Malta International Airport at Luqa, or arrive by ferry from Sicily.
- 2
Buses and cars to the Dingli ruts
The main island is small, and Malta Public Transport buses serve Dingli, Siġġiewi and Birżebbuġa from Valletta; a hire car or taxi is quicker for the Dingli area, where Misraħ Għar il-Kbir is a walk across open rock from the nearest road.
- 3
Ferry to Gozo for Ġgantija
Gozo Channel’s ferries cross between Ĉirkewwa on Malta and Mġarr on Gozo, and the nearest bus stop to Ġgantija is two minutes’ walk from the site.
- 4
Ħaġar Qim and Mnajdra on the south coast
Ħaġar Qim and Mnajdra, on the south coast near Qrendi, are the nearest of the temples to the Dingli ruts, and form one park with a visitor centre; a footpath of about 500 metres links the two, and the nearest bus stop is three minutes’ walk away.

The temples. Ħaġar Qim and Mnajdra, on the south coast near Qrendi, are the nearest of the temples to the Dingli ruts, and form one park with a visitor centre; a footpath of about 500 metres links the two, and the nearest bus stop is three minutes’ walk away. The Tarxien temples are near Valletta, a few minutes from the Hypogeum in Paola. Heritage Malta notes that parts of Ħaġar Qim and Mnajdra cannot be fully reached by visitors with limited mobility, while Ġgantija and Tarxien are fully accessible.
Book ahead for the Hypogeum. The Ħal Saflieni Hypogeum admits 10 people at a time, and Heritage Malta advises booking early. It caps a buyer at four tickets (families excepted). It also releases last-minute tickets the day before a visit, first come, first served, sold only at Fort St Elmo and the Gozo Museum of Archaeology until noon.
On the rut fields. Misraħ Għar il-Kbir is open ground, not a ticketed monument. There is little shade and little signage, and the rock is uneven and sharp; the fields around it are farmed.
When to go. Spring and autumn. In summer the open limestone is very hot by mid-morning, so go early. The ruts read best in low light, when their edges cast shadows.
At the beach. The State Department’s advisory for Malta warns that riptides have drowned tourists. Follow lifeguards’ instructions.

Common questions
What are Malta’s UNESCO World Heritage Sites?
Malta has three UNESCO World Heritage Sites: the City of Valletta, inscribed in 1980; the Ħal Saflieni Hypogeum, an underground burial complex in Paola; and the Megalithic Temples of Malta, for which UNESCO inscribed Ġgantija on Gozo in 1980 and added Ħaġar Qim, Mnajdra, Ta’ Ħaġrat, Skorba and Tarxien in 1992.
How old are Malta’s megalithic temples?
Malta’s megalithic temples date from the Neolithic: Wikipedia gives about 3600 to 2500 BC, and Heritage Malta dates the two structures at Ġgantija on Gozo to between 3800 and 2000 BC. The temples were claimed as the oldest free-standing structures on Earth until the discovery of Göbekli Tepe in Turkey.
What happens at Mnajdra temple at the equinox and solstice?
At Mnajdra, on Malta’s south coast, Heritage Malta notes that the doorway of the South structure is aligned with the sunrise at the spring and autumn equinoxes. At the winter and summer solstices, the rising sun’s beams pass along the sides of the main doorway, each time lighting a different decorated slab in the first chamber.
What is the Ħal Saflieni Hypogeum?
The Ħal Saflieni Hypogeum in Paola, Malta, is an underground burial complex of halls, chambers and passages cut into the limestone in three levels, in use from 4000 to 1500 BC by Heritage Malta’s dating. A stonemason found it in 1902; its deepest room lies 10.6 metres below the road, and Heritage Malta admits 10 visitors at a time.
Who built Valletta, and when?
Valletta, the capital of Malta, was begun in 1566 by the Order of St John, the year after the Ottoman siege of 1565, and is named after its founder, Grand Master Jean Parisot de la Valette. It stands on the Sceberras peninsula between Marsamxett and the Grand Harbour, and the Malta Tourism Authority says it was completed in 15 years.
What are the cart ruts of Malta?
Malta’s cart ruts are pairs of parallel grooves worn or cut into the islands’ bare limestone, found across Malta and Gozo. A typical rut is 10 to 35 centimetres deep, with 100 to 130 centimetres between the inside edges of a pair. At Misraħ Għar il-Kbir near the Dingli Cliffs they cross so densely that the site is nicknamed Clapham Junction.
How old are Malta’s cart ruts?
The age of Malta’s cart ruts is unresolved. The University of Malta, summarising the research, gives the predominant view that they were made in prehistory, between 5200 and 750 BC; other estimates run as late as the Middle Ages. The ruts cannot yet be dated directly, and the leading model, by Mottershead, Pearson and Schaefer in 2008, explains how they formed rather than when.
Do Malta’s cart ruts go into the sea?
Yes. A University of Malta study of how cart ruts are dated notes a pair that enters the sea and continues some distance under water, and ruts are recorded at St George’s Bay in Birżebbuġa, in south-east Malta. Ruts under the sea were made when that ground was dry.
