@anya.g.rowe: At the The Bishop's Palace & Gardens in Wells, Somerset, resident mute swans pull a hanging rope attached to a gatehouse bell to ask for food. This famous 170-year-old tradition started in the 1850s when a bishop's daughter first taught a swan to ring for lunch, and adult swans continue to pass the trick down to their cygnets. #somerset #bishopspalace #wells #wellscathedral #swans
