(); and the second Stravoskiadi, at . The full extent of capes and promontories take in Agia Aikaterini, Drastis to the north, Lefkimmi and Asprokavos to the southeast, and Megachoro to the south. Two islands are also to be found at a middle point of Gouvia and Corfu Bay, which extends across much of the eastern shore of the island; are known as Lazareto and Ptychia (or Vido). Diapontia Islands The Diapontia Islands (Greek: Διαπόντια νησιά) are located in the northwest of Corfu, (6 km away) and about 40 km from the Italian coast. The main islands are Othonoi, Ereikoussa and Mathraki. Lazaretto Island Lazaretto Island, formerly known as St. Dimitrios, is located 1.1 km of the coast northeast of Corfu; the island has an area of and comes under the administration of the Greek National Tourist Organization. During Venetian rule in the early 16th century, a monastery was built on the islet and a leprosarium established later in the century, after which the island was named. In 1798, during the French occupation, the islet was occupied by the Russo-Turkish fleet, who ran it as a military hospital. During the period of British rule, in 1814, the leprosarium was once again opened after renovations, and following Enosis in 1864 the leprosarium again saw occasional use. During World War II, the Axis Occupation of Greece established a Nazi concentration camp there for the prisoners of the Greek Resistance movement, while remaining today are the two-storeyed building that served as the Headquarters of the Italian army, a small church, and the wall against which those condemned to death were shot. Climate Corfu has a hot-summer Mediterranean climate (Csa in the Köppen climate classification). Biodiversity Flora Homer identifies six plants that adorn the garden of Alcinous: wild olive, pear, pomegranate, apple, fig and grape vine. Of these the apple and the pear are very inferior in Corfu; the others thrive, together with all the fruit trees known in southern Europe, with addition of the kumquat, loquat and prickly pear and, in some spots, the banana. Olive trees dominate and their combination with cypress trees compose the typical Corfiot landscape. When undisturbed by cultivation, the high maquis is the major natural vegetation type followed by deciduous oak forests and to a lesser extent, pine forests. In total more than 1800 plant species have been recorded. Fauna Corfu is a continental island; its fauna is
