Crannog on Loch Sguabain

Caisteal Eoghainn a' Chinn Bhig, Loch Sguabain, Isle of Mull, Scotland.
The name Caisteal Eoghainn a' Chinn Bhig means "the Caisteal of Ewen of the Little Head". This crannog has a defensive 3.3 m thick, dry-stone wall which surrounds an inner area of 22 m by 10m that probably contained domestic structures.
Ewen was killed during a 16th century battle between the Macleans and Maclaines, when his little head was cut off. This crannog is thought to be late medieval, and of artificial construction, but some believe it may have been a natural island. Another theory is that there may have been a causeway leading to it (see left of crannog) and that it may not have been an island at all.
