This episode, with guest Australian-based Diane Broinshtein, is one of two halves. Diane woke up early to talk about her trip with Ben to the oldest site in the landmarks book, Gough's Cave in Cheddar Gorge, where the remain of a Mesolithic (7100BC) man was found in the Victorian era. To balance the books, Diane's alternative landmark brings us right up to the 21 century with some famous street art.
