Garzes Tower (Maltese: Torri Garzes), also known as Saint Martin Tower (Maltese: Torri ta' San Martin), was a watchtower built in Mġarr, Gozo by the Order of Saint John in 1605. It was named after Martin Garzez, the Grand Master who financed its construction, even though it was eventually built after his death. The tower was demolished in the 19th century.
