During the past thousand years, whoever gained control of Fort St Angelo could effectively rule the Maltese Islands. Strategically located on a hillock, at the end of the Birgu peninsula, the fort dominates the Grand Harbour. During the Second World War, Fort St Angelo offered protection against Axis air raids and suffered 69 direct hits. After the war, the fort continued to serve as the headquarters of the Royal Navy in Malta, until the last detachment of foreign forces departed Fort St Angelo in March 1979. Fort St Angelo offers spectacular panoramic views of the Grand Harbour and its surrounding fortified towns. Through traditional and innovative immersive displays, visitors can experience the colourful history and various architectural styles of this fort, together with staggering examples of artillery.

The Inquisitor's Palace, situated in the heart of Vittoriosa, is one of the very few surviving palaces of its kind which, in the early modern period could be found all over Europe and South America. Many of these palaces simply succumbed to the ravages of time or were victims of the anti-reactionary power unleashed by the French Revolution. Fortunately, the Maltese Inquisitor's Palace, throughout its five centuries of history, always hosted high-ranking officials representing the main powers on the island, who therefore ensured its survival.

Notre Dame Gate is a grand baroque military gate built into the 17th century Cottonera Lines to protect the Three Historic Cities of Vittoriosa, Senglea and Cospicua. It is of monumental proportions being built on five levels. From its roof one can observe a good part of the island including Valletta and the whole of Cottonera. Over the centuries it has served as the main gate for the region, a military barracks, a gun powder magazine, a chapel, an air raid refuge and throughout World War One during and after the Gallipoli Campaign an extension to the nearby Cottonera Military Hospital. This gate now houses the headquarters of Fondazzjoni Wirt Artna - the Malta Heritage Trust. It is available for visiting once a week as part of a guided tour every Wednesday starting at 10am. This tour also includes a visit to the former Cottonera Military Hospital and parts of the Cottonera Lines.
