The chess-piece-like Red Tower was built in 1649 for Grand Master Lascaris, as part of the chain of signal towers that linked Valletta and Gozo; the view from its flat roof is stunning. This simple fortress is one of the more elaborate towers – it once housed a garrison of up to 49 men, and the walls are 4.5m thick. The plaque above the entrance indicates that this is not a place of sanctuary, despite containing a chapel. It's staffed by volunteers so is occasionally closed.
