The cave takes shape
Water enlarged cracks in the limestone, creating passages that later trapped layers of sediment and bone.

Għar Dalam
A cave where Malta's story can be read in layers - from Ice Age elephants and hippopotami to the islands' earliest known settlers.
A cave full of time
Għar Dalam is a cross-section through hundreds of thousands of years of Malta's natural and human history.
Its sediments preserve Ice Age elephants, hippopotami, deer, swans and smaller mammals. Higher layers contain pottery, tools and domestic animal remains from some of Malta's earliest farming communities.

Timeline
Before people, Malta was already changing
Għar Dalam links geological change, animal migration, island evolution and human settlement in one place.
Animals reach Malta
Lower sea levels made dispersal from Sicily easier. Elephants, hippopotami, deer and other animals reached Malta, then became isolated as the sea rose.
The first farmers
Upper deposits preserve pottery and domestic animal remains linked to some of Malta's earliest known settlers.
Scientific excavation begins
Genoese naturalist Arturo Issel carried out the first documented excavation, finding human and animal remains and establishing the cave's scientific importance.
The story is still changing
Research continues to reassess the cave's stratigraphy, fossil chronology and how sediments entered it.
The island rule
Island isolation can reshape body size: large herbivores may become smaller while some small species grow larger. Għar Dalam's elephants and hippopotami are part of that story.
Stratigraphy
Reading Għar Dalam layer by layer
Different deposits preserve different periods. Traditional layer names help explain the sequence, though modern research continues to refine their ages and interpretation.
The cave as an archive
Every layer answers a different question
Lower deposits record Malta before permanent settlement; higher layers preserve later Ice Age fauna, while the upper material records people, pottery and domesticated animals.
Older publications give very specific dates to individual layers. Heritage Malta's 2025 work re-examined the biochronology and stratigraphy, so the sequence is best read as an evolving scientific model rather than a fixed timeline.

A very different Malta
Elephants, hippopotami, deer, swans, dormice and carnivores reveal a Malta very different from today.
The upper cultural layer
Pottery and domestic animal remains mark the shift to farming communities arriving from Sicily.
Not just a fossil site
The dark inner cave remains habitat for an endemic woodlouse and roosting lesser horseshoe bats, helping explain why access is restricted.
What the fossils reveal
The fossils record changing sea levels, migration, isolation and evolution as well as the animals themselves.
Interpretation
What Għar Dalam tells us - and where the uncertainties remain
The cave is not a perfectly frozen record: excavation history and modern dating make the picture more complex.
Animals crossed during periods of lower sea level
The fossils show close links with Sicily. During colder periods, lower Mediterranean sea levels reduced the distance between landmasses and eased animal dispersal.
As sea levels rose, populations became isolated, contributing over generations to the distinctive island forms in Malta's fossil record.
Dates and layer boundaries are still being refined
Għar Dalam was excavated repeatedly from the nineteenth century, before modern recording and dating methods, and some deposits were disturbed or removed.
Recent research has revisited old records and the stratigraphy. The broad sequence is clear, but some dates and interpretations remain under study.
Visit plan
How I would explore Għar Dalam
The museum and cave work best as one story: seeing the fossils first makes the cave layers easier to understand.
Choose a stage
Stage 01 · Old Museum Hall
10-15 min
Start with the bones
The Victorian-style displays make the scale of the fossil record tangible.
- Look closely at the rows of fossil bones recovered during excavation.
- Compare the extinct island animals with the complete skeletons displayed nearby.
- Keep the dwarfing story in mind before reaching the geological layers.
Stage 02 · Interpretation Hall
10-15 min
Put the fossils into time
The newer displays connect the species, excavators and changing interpretations.
- Follow the sequence from pre-human Malta to the arrival of Neolithic farmers.
- Notice the range of animal groups rather than focusing only on elephants and hippopotami.
- Use the excavation history to see why the chronology has changed.
Stage 03 · The Cave
15-20 min
Read the cave wall
Only the first part of the 144-metre cave is open, but it is enough to understand the site.
- Look at the exposed sediment rather than only the shape of the cave.
- Notice fossil material still in situ and imagine how much was removed during earlier excavations.
- Notice how quickly the cave becomes darker and lower beyond the visitor route.
Għar Dalam is 144 metres long, but only the first 50 metres are open for safety and conservation.
Stage 04 · Gardens & Valley
10 min
Finish in the present-day landscape
The valley outside is a reminder that Għar Dalam is ecological as well as archaeological.
- Walk through the indigenous planting around the museum.
- Look across Wied Dalam and imagine the landscapes represented by the cave deposits.
- Remember that rare cave fauna survives beyond the public section.

Inside Għar Dalam
From the fossil collections to the cave, exposed deposits and surrounding valley. Tap any image to open it full-screen.
Għar Dalam's impact comes from its scale: a modest cave preserving vanished Ice Age ecosystems and the first communities who made Malta home.
Look at the sediment, not just the cave
The deposits are the archive; without the stratigraphy, the bones lose much of their meaning.
Notice what island life did to size
Small elephants and hippopotami show how isolation can reshape animal populations over time.
Do not rush the old display hall
The dense, old-fashioned rows of bones are now part of the site's museum history.
The cave is still alive
Rare invertebrates and bats inhabit its darker reaches, making conservation part of the modern story.
