Souda Bay is a bay and natural harbour near the town of Souda on the northwest coast of the Greek island of Crete. The bay is about 15 km long and only two to four km wide, and a deep natural harbour. It is formed between the Akrotiri peninsula and Cape Drapano, and runs west to east. The bay is overlooked on both sides by hills, with a relatively low and narrow isthmus in the west near Chania.
Near the mouth of Souda bay, between the Akrotiri and the town of Kalives, there is a group of small islands with Venetian fortifications. The largest island is Souda Island, giving its name to the bay.
Souda Bay is now a popular tourist destination although there are no formal public beaches designed in the area, due to the presence of the Crete Naval Base, a major naval installation of the Hellenic Navy and NATO in the eastern Mediterranean. Villages such as Megala Chorafia and Kalives afford fine views of the bay, and house-building, particularly for foreigners and tourist companies, is spreading along the bay.
There have been port facilities on the bay since ancient times, previously serving the city of Aptera. Aptera was founded in the 7th Century BC and was an important city during the ancient and early Byzantine periods. It was destroyed by the Saracens in the 820s AD. The nearest large ancient city was Kydonia, which flourished in the Minoan era on Crete; moreover, during a portion of the first millennium BC Kydonia held influence over Aptera.
The Venetians occupied the area in 1207. In 1571 an Ottoman military force landed at Souda and caused major destruction in the Chania area. The Venetians fortified Souda Island between 1570 and 1573, in order to protect the area from Ottoman raiders and pirates. However, Souda Bay remained a pirate infested area during the 15th, 16th and 17th centuries. The Venetians managed to hold on to the strategic islands within Souda Bay until 1715, over thirty years after the fall of Crete to the Ottomans.
