Watchtower in Lisburn Tce. The Watchtower was built in 1776 by a John Biss of Deptford Hall to check ship movements on a stretch of the river just above Wearmouth Bridge. Prior knowledge of ship arrivals was very useful to traders waiting for goods. It was probably of little value however as it became known as Biss's Folly and was demolished in 1903.
