Williamson Art Gallery and Museum. The Williamson Art Gallery and Museum is situated in Claughton, Birkenhead, Merseyside, England and houses the Wirral's art collection. Opened on 1 December 1928, the single-storey building is Neo-Georgian in style, and was deliberately designed to blend in with the local surroundings. Financial support for its establishment was provided by John Williamson, a Director of the Cunard Steamship Co. Ltd. and his son Patrick Williamson. Its collection includes Victorian oil paintings, including works by Albert Moore and Philip Steer, English watercolours, Liverpool Porcelain, and the UK's largest public collection of Della Robbia Pottery. It also has a large collection of ship models, focusing on Cammell Laird shipbuilders, the Mersey Ferries, and the vessels that used the River Mersey. The gallery also hosts regular exhibitions that can include work by nationally and internationally renowned artists. There are regular musical concerts and the gallery is also a venue for art and crafts workshops.
