Alexander Pope's Grotto, Radnor House School, Cross Deep, Twickenham, Middlesex TW1 4QG

Grade II* Alexander Pope's Grotto is the last remaining part of Alexander Pope's villa, which he built in 1720 on the banks of the Thames at Twickenham. The tunnel connecting the villa to Pope's gardens behind, was first decorated with bright stones as a 'Nymphaeum', but Pope's interests increasingly turned to raw nature and from 1740 until his death in 1744 he re-built it as a 'Museum' of minerals, many of which are still intact and visible today, A programme of repairs is on-going led by Pope's Grotto Preservation Trust. The grotto lies under Radnor House School, a cafe and river terrace are available for visitors
