Heritage Open Day: We welcome craftspeople to the Bishop's Waltham Palace and Museum for the day! A number of craftspeople will be visiting the museum for the day to show their skills and their objects. Come and meet them in the beautiful setting of Bishop's Waltham Palace, a brilliant place for a picnic and a wander around. The museum will be open all day with information on the Palace and the medieval town of Bishop's Waltham, including the Railway200 exhibition on the branch line.
