The fortifications of Senglea are a series of defensive walls and other fortifications which surround the city of Senglea, Malta. The first fortification to be built was Fort Saint Michael in 1552, and the majority of the fortifications were built over the next decade when it was founded by Grand Master Claude de la Sengle. Modifications continued until the 18th century, but large parts of the fortifications were demolished between the 19th and 20th centuries.
