Neptune Hall, National Maritime Museum, Romney Road, SE10 TQ 3860 7766 MOLAS (Julian Bowsher) evaluation Oct 1996 National Maritime Museum NPH96
Two trenches within the Hall revealed natural gravels overlaid by the silts of a former topsoil; it contained material dated to 18th-19th c. Above the topsoil lay a mortar or plaster surface that seems to have predated the 1873 construction of the Hall and was probably connected with the former use of the site as a gymnastics ground. A third trench to the E of the Hall revealed a wall which is likely to have been associated with outbuildings depicted on a site plan of 1844.
