Dun Hallin is an Iron Age broch located on the Waternish peninsula of Skye. Dun Hallin has an external diameter of around 17.4 metres and an internal diameter of around 10.5 metres. The broch walls currently stand to a maximum height of 3.8 metres on the north and west sides. The entrance is on the southeast side but is in a ruined state. On each side of the entrance passage are oval guard cells, although only the northern, right-hand cell can easily be seen. The interior of the broch is full of rubble, much of it grassed over. A mural gallery is visible on the southwest side and a lintel stone remains in position over the doorway there. Six steps of the intra-mural stairway were found when the broch was examined in 1921 but are not now apparent. The broch is additionally defended by an outer stone wall which runs round the edge of the rocky knoll and which is still about 6 metres high to the south. The broch has not been excavated.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
