Wignacourt Tower (Maltese: Torri ta' Wignacourt), also known as Saint Paul's Bay Tower (Maltese: Torri ta' San Pawl il-Baħar), is a bastioned watchtower in St. Paul's Bay, Malta. It was the first of six Wignacourt towers to be built, and the first stone was laid on 10 February 1610. It replaced the role of Ta' Tabibu farmhouse which was previously known as Dejma Tower. An artillery battery was added a century later in 1715. Today the tower is a museum of fortifications around the Maltese Islands.
