Stac Dhòmhnaill Chaim

In 2003 and 2006, an archaeological team of rock climbers scaled the promontory and documented the site; finding in 2006 a piece of possibly Neolithic pottery.

Stac Dhomnuill Chaim when translated from Scottish Gaelic means "One-eyed Donald's stack".

It is a promontory fort located near Mangursta on the west coast of the Isle of Lewis in the Outer Hebrides (grid reference NB00223152).

The 19th-century historian F W L Thomas stated that there were stories in Uig that recounted how Donald Cam's daughter, Anna Mhòr ("big Anne"), would carry water to her father upon her head because her hands were required to climb the treacherous path to the top.

He described the promontory as almost cut off from the nearby shore by a very deep ravine, though it remained connected to the mainland by a rocky isthmus.

The Investigator's observations from the opposite cliff concluded that the site seemed to appear as Thomas's plans had showed it in the late 19th century.

The remains of structure A are of a circular, turf and stone building measuring to about 2 metres (6.6 ft) in diameter.

[7] These investigations led the archaeologists to conclude that, depending on winter storm conditions, it is possible that in the next two decades the site might be totally destroyed by erosion and collapse of the stack.
