Long Island is an island in Langstone Harbour in Hampshire, England.[1] It is 750 metres (820 yd) long and up to 250 metres (270 yd) wide.[2] Three bronze age pots have been found on the island as has Mesolithic and late neolithic flint-work.[2] Bronze age pottery along with smaller amounts of Romano-British pottery have been found on the island.[2]
In 1978 the island along with the other islands in Langstone harbour was acquired by the Royal Society for the Protection of Birds who turned it into a bird sanctuary.[3] Since that time unauthorised landings have been forbidden.[3]
