The Bristol Blitz was the heavy bombing of Bristol, England by the Nazi German Luftwaffe during the Second World War. Due to the presence of Bristol Harbour and the Bristol Aeroplane Company, the city was a target for bombing and was easily found as enemy bombers were able to trace a course up the River Avon from Avonmouth using reflected moonlight on the waters, into the heart of the city. Bristol was the fifth-most heavily-bombed British city of the war.

Castle Park is a public open space in Bristol, England, managed by Bristol City Council. It is bounded by the Floating Harbour and Castle Street to the south, Lower Castle Street to the east, and Broad Weir, Newgate and Wine Street to the north. Its western boundary is less obviously defined and has been the subject of controversy, perhaps because the area around High Street and St Mary le Port Church, though not part of the park and always intended for development, is often considered at the same time as the park.
