The Fortifications of Malta are a series of defensive structures built to protect the islands of Malta from invasions. These fortifications date back to the Knights of St. John in the 16th century and include impressive walls, bastions, and towers. The most notable fortifications are found in the capital city, Valletta, which was designed as a fortified city. Key examples of these fortifications include Fort St. Elmo, Fort Ricasoli, and the City Gate. The walls and fortresses played a crucial role during historical conflicts, such as the Great Siege of Malta in 1565, showcasing the strategic importance of Malta in the Mediterranean.
