What is "haslar"

Haslar is on the south coast of England, at the southern tip of Alverstoke, on the Gosport peninsula, Hampshire. It takes its name from Anglo-Saxon hæsel-ōra = " hazel - landing place". It may have been named after a bank of hazel strewn on marshy grounds around Haslar Creek to make it passable and habitable in old times, or merely because hazel grew there.
