Portland Museum

Portland Museum is a museum on the Isle of Portland in Dorset, southern England. It is located at the southern end of the hamlet of Wakeham. The museum is housed in two 17th-century thatched cottages, which have both been Grade II Listed since 1951. One of the museum's cottages, Avice's Cottage, is featured in Thomas Hardy's 1897 novel The Well-Beloved, as the home of three generations of "Avices" - the novel's heroines.

Portland Museum was founded by Marie Stopes, who purchased the museum's two cottages, then derelict, in 1929. She then donated them to Portland as a museum which opened in 1930. Stopes was the first honorary curator and continued her association with the museum until her death in 1958.
