An archaeological watching brief during demolition works and other groundworks at the Wish Tower Café, Eastbourne, did not reveal any surviving evidence for the Emergency Coastal Battery that was located at the site during the Second World War. The watching brief demonstrated that the concrete slab floor of the demolished café is a suspended floor with cavities below. It is suggested that remains of the Emergency Coastal Battery and earlier archaeological remains may well be preserved below this suspended floor. Work adjacent to the Counter Scarp Wall revealed a complex stratigraphy of made ground, all probably of 19th century material, and the foundations of the Counter Scarp Wall, together with a wall and floor of unknown date and purpose.
