The Three Cities refers to the three fortified cities of Cospicua, Vittoriosa, and Senglea, which are enclosed by the massive line of fortification created by the Knights of St John.
You will first visit Cospicua, approximately 30 minutes away from Valetta. It is the largest of the Three Cities. Its maritime facilities started during ancient times around 600 B.C. In 1776 the Order of St. John began a dockyard, which was to play a vital role in the development of this city. During the reign of the British Empire, the navy made great use of the dockyard, particularly during the Crimean War, the First World War, and the years preceding the Second World War. As you drive through this area you will be able to see the majestic bastions.
You will then drive to Vittoriosa, also known as Birgu, a very old locality on the south side of the Grand Harbor with origins reaching back to medieval times. The town sits on a promontory with Fort St. Angelo at its head. After visiting this area you will walk down to the waterfront.
You will board your motorized boat for a cruise of the Grand Harbor. The harbor was the base for the Knights of St John for 268 years, and then a strategic location for the British for a further 170 years. The area was the scene of much of the fighting in the First Siege of Malta and the whole area was savagely bombed during World War II. During your 30 minute cruise, your guide will share with you the history and sites of the harbor.
Returning to dry land, you will visit Senglea the last of the three cities. With an area of just over half a square mile, it is Malta's smallest and also its most densely populated area. Up until the Second World War (and its bombing) it was the center of Malta's elite and intelligentsia. In recent years, rehabilitation of the waterfront as a yacht marina and the renovation of various houses has made it a sought after neighborhood again. You will then return from Senglea to Valetta.
