Spinalonga, the last leper colony in Europe, is located in Elounda from where we take the boat for Spinalonga island. Originally, Venetians fortified the islet in 1579, by building a fortress with 40 cannons and they are actually the best preserved walls in Europe. It used to be a leper colony from 1903 until 1957, where lepers could have a better life, medical help and economical support. The ruins of the market street with the shops, the hospital and many small houses in which lepers lived isolated, can be explored individually.
