Dun Telve Broch - Glenelg
The most impressive Iron-age buildings remaining today are the Brochs.
Brochs are twin-walled circular structures with a single doorway; off to the side of the doorway is a short passage between the walls which may have housed a guard or watchdog. Once within the inner enclosure, there is also an inner entrance leading to other passages between the curtain walls, and parts of the stairways still survive which gave access to upper levels.
Inside Dun Telve the Broch stood around 10 metres high. There are remains of wooden post holes at various points in the structure, and it is thought that the inner circular courtyard may have been roofed, giving comfortable living accommodation during times of attack; much more pleasant that the passageways in the curtain walls.
