A vitrified (burnt so fiercely that the stone melted and set again) Iron Age (from about 800 BC until the Romans came) fort with a later dun built directly over it in at least two phases, giving one hillside a compressed record of centuries of rebuilding.
On a steep-sided knoll rising some 60 metres above the shore of Loch Snizort, a ring of ruined stone walls looks west across the water from Skye’s Trotternish peninsula. Parts of the wall are fused into a hard, glassy mass, the scar of a fire so intense it melted the rubble core together — a process archaeologists call vitrification, and one of the more dramatic things a fort’s stonework can preserve.
The knoll carries more than one building on top of the other. An early fort enclosed an oval area of roughly 150 feet by 120 feet within a wall about 10 feet thick, and at some later date a dun (a smaller, thick-walled stone stronghold) was raised directly over it, adding an outer wall some 320 feet long to the east and two shorter walls to the north, with an entrance set between them. Even the dun itself was not built in one go: careful reading of the stonework shows poorer-quality walling to the west, south and south-east, suggesting a second, later phase of work.
No excavation has dated any of this precisely. What survives is a layered ruin whose builders reused, extended and patched the same commanding position above the loch more than once, leaving the sequence of construction to be read from the stones themselves rather than from any written record.
What follows is drawn from published sources, with each claim labelled by how firmly it is established.
History
In the prehistoric period, most likely during the Iron Age, a fort was raised on the knoll above Loch Snizort, its wall built up to some 10 feet thick to enclose an oval area of roughly 150 feet by 120 feet. At some point the timber-laced stonework caught fire and burned so fiercely that sections of the wall fused into a hard, glassy mass, a process called vitrification whose cause remains debated among archaeologists studying Scotland's forts.
At a later date a dun was built directly over the earlier fort, reusing the same commanding position above the loch. The new structure added an outer wall running about 320 feet along the east side, with two shorter walls to the north and an entrance set between the outer wall and the eastern one, reshaping the earlier fort into a more elaborate, multi-walled stronghold overlooking the water.
Close study of the stonework suggests the dun itself was built in at least two separate stages: an earlier phase of well-laid walling, and a later, poorer-quality addition traceable along the west, south and south-east sides. This uneven build quality points to the site being reworked or repaired over time rather than completed in a single campaign, though nothing fixes exactly when each stage took place.
In more recent times Dun Skudiburgh has been recorded in national reference databases, including Wikipedia and Wikidata, which preserve its measurements, location and structural description for public reference, even though no excavation report has been published to date its construction more precisely.

A dun built over a vitrified hillfort
The later dun reworked an earlier hillfort whose timber-laced wall had been vitrified by intense fire, creating a multi-phase fort above Loch Snizort.

Both are defended prehistoric sites on Skye, but Dun Skudiburgh is a hillfort while Dun Hallin is a broch; their relationship is comparative rather than institutional.

Discovery & excavation
No excavation of Dun Skudiburgh has been recorded. What is known comes from surface survey of the surviving walls, which has identified vitrification in the earlier fort and at least two phases of building in the dun from differences in wall quality, without fixing a date for either stage.
What to look for
-
Vitrified walling
Sections of the earlier fort's wall have fused into a hard, glassy mass where intense fire melted the stone core together.
-
The oval enclosure
The inner fort wall, about 10 feet thick, encloses an oval area roughly 150 feet by 120 feet on the knoll's summit.
-
The east outer wall
A wall around 320 feet long runs outside the fort to the east, added when the dun was built over the earlier structure.
-
Two north walls and an entrance
Two shorter walls lie to the north, with an entrance set between the outer of these and the wall to the east.
-
Poorer-quality secondary walling
Along the west, south and south-east, lower-quality stonework marks what is thought to be a second, later phase of building.

Questions people ask
- What is Dun Skudiburgh?
- A prehistoric fortified site near Uig on Skye, consisting of a partly vitrified Iron Age fort overlaid by a later stone dun on a steep knoll above Loch Snizort.
- What does 'vitrified' mean?
- It describes stone fused into a hard, glassy mass by intense heat, likely from a fire in the fort's timber-laced wall core, and is found in part of the site's inner wall.
- How big is the site?
- The inner enclosure is roughly 150 feet by 120 feet within a wall about 10 feet thick; an outer wall to the east adds a further 320 feet of walling.
- Was it built in one go?
- No. It shows at least two construction phases in the dun, identified from poorer-quality walling to the west, south and south-east compared with the rest of the structure.
- Where exactly is Dun Skudiburgh?
- On a steep-sided knoll about 60 metres above the shore of Loch Snizort, on the west coast of the Trotternish peninsula on Skye, near Uig.
