Mercia Agamemnonos
It is a place that is under the protection of UNESCO.
If you visit during winter time it will be filled with water. During summer it dries up. In earlier years it was connected with the sea, and locals used to get salt from the lake.
If you are lucky you may get to see flamingos. Until the early 90s swans used to visit the lake during the winter. Nowadays is a really rare thing.
