It is volunteer-run and is open April to October part of the Tain Through Time visitor centre.

Rosemary Mackenzie had been asked to organise an exhibition of local material for the celebration of the 900th anniversary of Tain's royal charter in 1966.

The museum is the custodian of a papal bull from Innocent VIII dated 17 July 1492.

There was a large and active local East Ross population in Pictish times, (approximately 50BC to 900AD).

The museum forms one part of the larger visitor centre on the site, the whole of which is called Tain Through Time.
