According to researchers, the Castle of Kyparissia was built by Frankish people on the site of a previous Byzantine fortress.
The Byzantines had built four bulwarks at the four corners of the castle, but only one is preserved today, which is named Ioustinianos, after the great Byzantine emperor. The Franks attacked the Castle in the 13th century and kept it under their control for two centuries. As it is built on a hill overlooking the whole town and bay of Kyparissia, this Castle was a watch outpost for enemies and pirates.
In 1460, the Castle of Kyparissia was conquered by the Turks, until the 1820s, when the Greek War of Independence set the town free. However, due to the battles that have occurred, the Castle has been greatly damaged. Most of the bulwarks, the walls, the cisterns, and the storehouses have been destroyed either by attacks or from the gradual decay.
In 1970, there was an effort by the Greek government to restore the Castle. A small open-air theatre was built, which now hosts occasionally a number of cultural events, such as musical concerts, poetry nights and ancient tragedies. In summer, there is a refreshment stand where you can enjoy a cool drink while you see the great view of the surrounding area.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
