The Three Cities is a collective description of the three fortified cities of Cospicua, Vittoriosa, and Senglea on the Island of Malta, which are enclosed by the massive line of fortification created by the Knights of St John, the Cottonera Lines. 

 

COTTONERA 

 

Cottonera (Bormla) is a double-fortified harbour city on the Mediterranean island of Malta. It is the largest of the Three Cities. It was also given a title as Citta' Cottonera, but erroneously the title is now used to define the whole region. It is situated between the other two towns which make up Cottonera which are Vittoriosa (Birgu) and Senglea (Isla). These three towns form part of the area surrounding the Grand Harbour and are found on the eastern side of the capital city Valletta. 

 

Cospicua was inhabited since Neolithic times and the last to be fortified. Its lines of majestic bastions, built by the Knights of Malta, are a sight to behold for sheer size and magnitude. In 1722, Grand Master Marc'Antonio Zondadari declared it a city and in view of its strong bastions named it Città Cospicua. 

 

VITTORIOSA 

 

Vittoriosa (Birgu) is a very old locality on the south side of the Grand Harbour in Malta with its origins reaching back to prehistoric times. The town occupies a promontory of land with Fort St Angelo at its head and the city of Cospicua at its base. The city played a vital role in the Siege of Malta in 1565. 

 

Birgu is ideally situated for safe anchorage, and over time it has developed a very long history with maritime, mercantile and military activities. Prior to the establishment of Valletta as capital and main city of Malta, military powers that wanted to rule the Maltese islands would need to obtain control of Birgu due to its significant position in the Grand Harbour. Phoenicians, Greeks, Romans, Byzantines, Arabs, Normans, the Angevines, the Aragonese and the Knights of St. John all contributed to the development of Birgu. 

 

SENGLEA 

 

Senglea (Isla) is a fortified city in the east of Malta, mainly in the Grand Harbour area. It is one of the Three Cities, with the other two being Cospicua and Vittoriosa. The city of Senglea is also called Citta Invicta, because it managed to resist the Ottoman invasion at the Great Siege of 1565. The proper name is Senglea since the grandmaster who built it Claude De La Sengle, gave this city a part of his name. 

 

The island was in fact joined by a landbridge to Cospicua during the time of the Knights of St. John and as a result, it became peninsular in shape. During the time of the Knights of St. John, Senglea was also used as a hunting area, and was in fact known as L'Isola di San Giuliano, but later it was developed and made inhabitable by the Grand Master, Claude de la Sengle who built fortifications following a Turkish invasion in 1551. The locality eventually became known as Senglea but retained its old name Isla.
