About Us

Our Background

The Museum was set up through the enthusiasm and vision of the late Arthur Allan. It is operated by a Trust and is a Registered Charity. A recent legacy from MissSignpost Josephine Bennett, a founder member, has allowed the Trust to extend the range of exhibits and develop its service to the local community.

The first venture was a limited exhibition, mainly of models of Clyde steamers and items associated with them, which was set up as part of the Argyll Hotel. This proved to be too restrictive, and the offer by Argyll and Bute Council of part of the Castle House at a nominal rent was gladly accepted. Many months of hard work by devoted local volunteers and the generosity of members of the community in donating or lending articles produced a Museum which tells the story of Cowal from the Stone Age to the American nuclear submarines.
