GET TO KNOW AVONCROFT Our history In 1967 Avoncroft Museum was opened to the public following the rescue and reconstruction of a medieval Town House from Bromsgrove, and soon became England’s first open-air museum. Then, as now, our priority was to retain historic buildings in their original location. Over five decades, Avoncroft Museum has continued to rescue structures and the Museum now displays and cares for over twenty five historic buildings that range in date from Worcester Cathedral’s fourteenth century Guesten Hall roof to a post second world war prefab from Birmingham – covering over 700 years of Midlands history.
