Abandoned: Mid-20th Century
Eerie Elements: After being carved off Crete to be a fortress, Spinalonga — sometimes called the Island of Tears — last served as a leper colony in the 20th century.
Can You Go? While once lepers shuddered to enter the island’s isolation through “Dante’s Gate,” now tourists are welcomed for visits with open arms, as long as they leave before the day is out.
