Heritage Open Day: Enjoy free entry at Seaford Museum on September 13th. Free entry to Seaford Museum. Much bigger than it looks, there is so much to see inside. Objects and information relating to the history of Seaford, and general social and domestic history. A parade of shops and rooms from Victorian times to World War II show off the artefacts in a contemporary setting. This year, we have an exhibition of local artist Harry Harison Evans' pen and ink drawings of local sites in the 19th and early 20th centuries.
