Summary from English Wikipedia (enwiki)

Benn's Island, previously named Church Eyot, Kember's Eyot and sometimes referred to as Benn's Ait, is a private 0.1-acre (0.040 ha) ait (island) on the River Thames south-west of London. It is among a string of narrow islands above Molesey Lock and due to its clubhouse and size — the second-smallest named island on the Thames — it has deep foundation pilings to raise the building more than 1 m above the water line.
