Wignacourt Tower (), also known as Saint Paul's Bay Tower (), 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. Wignacourt Tower was the second tower to be built in the Maltese islands, after Garzes Tower on Gozo. It was also the first tower to be built on the main island. As Garzes Tower was demolished in 1848, Wignacourt Tower is now the oldest surviving watchtower in Malta. History By the end of the 16th century, Malta's harbour area was extensively fortified. However, the rest of the islands was virtually undefended, and the coastline was open to attacks by Ottomans or Barbary corsairs. This began to change in the early 17th century, when Martin Garzez, Grand Master of the Order of Saint John, allocated funds for the building of Garzes Tower on Gozo. Garzes' successor, Alof de Wignacourt, set out to build a series of towers around the coastline, which were personally funded by him and came to be known as the Wignacourt towers. The first tower was built to protect St. Paul's Bay, and was called Wignacourt Tower after the Grand Master. On 7 November 1609, plans and a model of the tower were presented to the Order's council. The first stone of was blessed and laid on 10 February 1610, and the accompanying ceremony was personally attended by Wignacourt himself. The tower cost 6748 scudi, 7 tari and 10 grani to build. Although there are claims that the tower was designed by Vittorio Cassar, he disappears from the Order's military records in around 1603. Cassar died in around June 1609, before work on the tower began. The architect of Wignacourt Tower was probably an unknown Maltese capomastro. The tower was the only major fortification in the north of Malta until the construction of Saint Agatha's Tower in 1649. It had Qawra Tower (built 1638), Buġibba Battery (built 1715) and Mistra Battery (built 1761) in its line of sight. A coastal battery was added to the tower in 1715 to house two 18-pounder guns. Buttressing was added to the lower half
