The oldest remaining part of the harbour is the "Auld Kirk Green" or "Anchor Green", which lies on the opposite site of the original harbour island from the dock. St. Andrews Kirk (church) - which excavations have revealed was built on the foundations of an older church or pagan temple - was built in 1177 and used by pilgrims to pray for safe passage across the water. It later became the North Berwick Parish Church, which precipitated the construction of first a bridge and finally a causeway to the harbour island.
