Lasithi
Lasithi () is the easternmost regional unit on the island of Crete, to the east of Heraklion. Its capital is Agios Nikolaos, the other major towns being Ierapetra and Sitia. The mountains include the Dikti in the west and the Thrypti in the east. The Sea of Crete lies to the north and the Libyan Sea to the south. To the east of the village of Elounda lies the island of Spinalonga, formerly a Venetian fortress and a leper colony. On the foot of Mount Dikti lies the Lasithi Plateau, famous for its windmills. Vai is well known for its  datepalm forest. Thanks to its beaches and its mild climate year-long, Lasithi attracts many tourists. Mass tourism is served by places like Vai, Agios Nikolaos and the island of Chrissi. More off-beat tourism can be found in villages on the south coast like Myrtos, Makrys Gialos or Makrigialos, Xerokambos and Koutsouras. Lasithi is home to a number of ancient remains. Vasiliki, Fournou Korifi, Pyrgos, Zakros and Gournia are ruins of Minoan date, Lato and Itanos were Doric towns. History. The history of Lasithi can be traced over at least three millennia. The region has considerable ancient history antecedents , including the Dorian era settlement of Olous and Lato. Etymology. It has been speculated that "ra-su-to", found in Linear B, corresponds to an unattested ancient "Lasynthos". There is also a Lyttian tribal name "Lasynthioi", presumably reflecting the same name. Earlier proposals that it is derived from a Venetian 'la' preposed to derivatives of "Lyttos" ("Lyttus" > "Tselyttus" > "Tselethe" > "Xeethe" > "La Xeethi" > "Lasithi") or "Sitia" ("Sitia" > "La Sitia" > "Lasithi") are unlikely, as the name Lasithi was attested as early as 1211, whereas the Venetians only first arrived in Crete in 1205. Another unlikely  etymology derives it from "lakkos" 'hole or basin' ("Lakkos" > "Lakkidion" > "Latsidi" > "Lasidi" > "Lasithi"). Administration. The regional unit Lasithi is subdivided into four municipalities. These are (number as in the map in the infobox): Prefecture. As a part of the 2011 Kallikratis government reform, the regional unit Lasithi was created out of the former prefecture of Lasithi (), which was created while Crete was still an autonomous state and was retained after the island joined Greece in 1913. The prefecture had the same territory as the present regional unit, except Viannos area that belonged to Lasithi but was  annexed to Heraklion prefecture in 1932. At the same time, the municipalities were reorganised, according to the table below. Provinces. Before 2006, Lasithi was divided into 4 provinces:
