Blakeney was a commercial seaport until the early 20th century. Now the harbour is silted up, and only small boats can make their way out past Blakeney Point to the sea. The harbour and surrounding marshes are owned by the National Trust and is a nature reserve where seals can be seen basking on the sand.
Just inland from the harbour is Mariners Hill. This vantage point is believed to be man-made, probably as a lookout point for the harbour. Adjacent to the hill, at the foot of the village’s High Street, is the old Guildhall with a 14th-century undercroft.
Higher up the village, the Church of Saint Nicholas has two towers: the main tower is over 100 ft (30 m) high and a well-known landmark for miles around, and the smaller tower was built as a beacon to guide boats into Blakeney harbour.
