Join as a member for year-round events

Oxford Preservation Trust does so much more than organise Oxford Open Doors. We look after 1,000 hectares of green spaces in Oxford and care for buildings like Oxford Castle & Prison and the Rewley Road Swing. We want to make Oxford's history and heritage accessible to everyone in our beautiful city, across town and gown. The health and well-being of Oxford is at the heart of our work, looking after its heritage and green spaces.
