Seaham, formerly Seaham Harbour, is a small town in County Durham, situated south of Sunderland and east of Durham. It has a small parish church, St Mary the Virgin, with a late 7th century Anglo Saxon nave resembling the church at Escomb in many respects. St Mary the Virgin is one of the 20 oldest surviving churches in the UK. Seaham is currently twinned with the German town of Gerlingen.
