Lambehythe
Lambeth is a district in London, England, situated in the southern part of London, just across the River Thames from the city center.
Malory names it as the location of Sir Meleagant’s castle, which in other legends is in Gorre.
Then Sir Launcelot... took the water at Westminster Bridge, and made his horse to swim over Thames unto Lambeth.
