Church Island is an island in the River Thames in England on the reach above Penton Hook Lock, near Staines Bridge in Staines, Spelthorne, Surrey. It connects by a footbridge to Church Street, Staines, near a recreation ground.
Roman Bridges across the Thames were built here soon after the invasion of Claudius in 43 AD. The Roman name for Staines was "ad Pontes" (plural "at the bridges") implying that there was more than one bridge. It is believed that these bridges crossed the River Colne and the Thames via Church Island.[1]
