A wealth of finds indicating signs of habitation stretching from the Protocycladic era until the 7th-8th century AD have been unearthed by archaeologists at Vryokastro on the island of Kythnos, the site of an ancient city, and the nearby islet Vriokastraki that was once connected to the island by a narrow isthmus.
The excavation work was carried out over the summer, from June 24 until August 4, and finds include a early Christian basilica with later additions, including two towers and strong exterior walls, a number of rectangular rooms partly carved from rock that were used until late antiquity and obsidian tools and pottery shards of the Protocycladic era.
The latter provide the first definitive proof of a 3rd millenium BC Protocycladic settlement on Vryokastraki, according to an announcement by Cyclades Antiquities Ephorate and Thessaly University, which noted that some of the stone-carved rooms may also date back to this time.
It also noted evidence that the location was resettled in the 12th century BC after a period when it was abandoned, and then continuously inhabited from that time until the 7th or 8th century AD since all subsequent eras are represented by finds unearthed on the site.
The city, which archaeologists believe was based on the islet, started to shrink in the early Byzantine period and was finally abandoned, with the remaining inhabitants moving to the fortress now known as Orias Castle.
