A remarkable example of a Pictish stone clearly illustrating a wild boar, the Knocknagael Boar Stone has been relocated to within Highland Council Headquarters in Inverness where it can be seen through the glass of a window, along with an interpretation plaque provided by Historic Scotland. The stone was originally to be found at the roadside near Knocknagael, 2½ miles (4 km) south of its present location, but was moved in 1991 to protect it from weathering and vandalism.
Described as a Class I Pictish Symbol Stone, this rough monument was carved between 700 and 800 AD, and show a fine example of a boar, typical of the simple Pictish art of the time. The muscles of the beast are emphasised with spiral markings. The stone also portrays a mirror-case, a symbol associated with the highly-polished mirrors dating from the Iron Age. The purpose of this type of stone is unknown; it may have marked a boundary or the grave of someone of high status, or may have been a monument recording a marriage.
The stone is protected by Historic Environment Scotland on behalf of the Scottish Ministers.
