Driven past this a number of times recently (currently working nearby), and will endeavour to bring a camera with me soon and get some photos.
The Clach a'Mheirlich or 'Thief's Stone' (Pictish Symbol Stone Class 1) stands in a field by the Alness to Invergordon road. On the front is an incised step symbol and on the left side what appear to be the traces of a crescent symbol with a pair of pincers below.
Park in the 'Public slipway' car park. The stone is about 20m into the field across the road.
Antiquities. - Under this head, it may be mentioned, that, in a field a little to the west of the church, there is a singular upright stone, somewhat in the form of an obelisk, called Clach a Mhearlich, i.e. the thief's stone, - which is evidently of very ancient date. Though in the midst of an arable field, it is most religiously preserved, no attempt being made to remove it, or alter its position. None even of the oldest inhabitants are acquainted with any distinct tradition, respecting its origin or intention; but, from the name, it is conjectured that some noted robber was buried beneath it.
