Dun Carlowayとは 意味・読み方・使い方

Dun Carloway (in Scottish Gaelic Dùn Chàrlabhaigh) is a broch situated in the district of Carloway, on the west coast of the Isle of Lewis, Scotland. It is a remarkably well preserved broch - on the east side parts of the old wall still reaches to 9 metres tall. In places there are also more modern repairs to the east wall. Dun Carloway was probably built some time in the 1st century BC, and radiocarbon dating evidence from remains found in the broch show that it was last occupied around 1300 AD. At the base the broch is around 14 to 15 metres in diameter and the walls around 3 metres thick. It has a circular plan and hollow walls and was built without mortar. It probably had wooden floors, internal partitions and a thatched roof, necessary to make it habitable, but the only remaining evidence of this are post-holes. Together with the roof, the narrow passageway presumably secured by a wooden door, were the most vulnerable points of the building, especially to fire.
