Kaliakra is a long and narrow headland in the Southern Dobruja region of the northern Bulgarian Black Sea Coast, located 12 km east of Kavarna and 60 km northeast of Varna. The coast is steep with vertical cliffs reaching 70 m down to the sea.
In 4th century BC a settlement called Tirrisis was founded bearing the name of a local Thracian tribe. In Roman times the fortress rapidly grew – lots of public buildings and facilities were built. There were plumbing system, churches, public baths (Roman thermes), fortification walls most of which can still be seen today. The cape became a strong Bulgarian fortress and flourished in the second half of the 14th century as a capital of the Dobrotitsa dukedom. It was a powerful medieval town minting its own coins. The fortress declined when it was conquered by The Ottoman Empire.
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.
