The Dwejra Coast Watch-Tower was built during the reign of Grand Master Anton de Paule in 1651 but was completed
during the reign of Grand Master Jean Paul Lascaris de Castellar a year later.
After 1744, apart from spying on Turkish raiders, Dwejra Tower acquired another function - that of guarding the
Hagret il-General and the supposed medicinal fungus that grew on it.

After 1873 the tower ceased to act as a coast guard and was deserted.
