Located in the Kaylaka Park a few kilometers away from Pleven, Storgosia is ancient fortress dating back to the Roman era and containing the ruins of towers, gates, residential houses, a public storehouse and a large church believed to be constructed around the 4th century. Originally built as a road stop, it became a fortress to protect itself from raids and attacks.
The fortress existed until the end of the 6th century, when the settlement of the Slavs apparently led to its abandonment and during the rule of the Ottoman Empire the fortress was practically destroyed (probably in the 16th century), so that the stones could be used for the construction of a wall around the Turkish barracks in Pleven.
Archaeological excavations have been carried out on the site and a few basic structures of buildings can be seen.
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.
