The Fortress Builders - Fortifications Interpretation Centre

Tucked near St. Andrew's Bastion in a late 16th-century warehouse, this centre digs deep into Malta's extraordinary fortification history — one of the most remarkable in the world. You'll get cross-sections of towers built by the Knights of St. John, with exhibits that actually explain why these walls were designed the way they were, not just that they exist. It's a surprisingly focused and intelligent museum that goes well beyond a generic history lesson.
