Excavations at Golitsa, near Varna, in 2005
The Roman boundary along the Stara Planina range between Obzor and the Eleshnitsa River represents massive fortified walls, reinforced with towers at certain places. The defensive sector at Golitsa played a major role in the East Balkan boundary. It comprised three individual fortresses connected by fortified walls. The middle fortress was the biggest; it was excavated in 2005. It has a regular octagonal ground plan and symmetrically situated towers and gates. It has probably been built in the first half of 5th century AD, and had existed until the late 6th or the early 7th century AD.
