Dùn Othail, a rock stack near North Tolsta, was first described as a natural fort in 1696, then in 1852 as the site of the ruins of a house said to have been erected and inhabited by an outlaw, and then in 1861 as a possible early chapel.

 

The site is linked to the Clan Morrison, and is within the ancient boundaries of Ness, the clan's traditional home.

 

There are remains of a small drystone building of early Medieval date on the stack which is split from the mainland by a perpendicular ravine.

 

The rock, rising 60m above sea level, is only accessible from the SE.
