Golyamo Gradishte, Mountain summit in Strandzha, Bulgaria

Golyamo Gradishte is a mountain summit in the southeastern Strandzha range, standing at approximately 710 meters elevation. The peak can be reached via marked hiking trails that connect to several nearby villages in the area.

A Thracian fortress with a round citadel stands on the summit, its wall built of dry-laid broken stone. The wall foundations are 2.5 m thick and the citadel measures 100 m across. An altar to Apollo Aulariok was found at its centre, and rock-cut markings survive on the rocks about 30 m from the peak.

The peak's name comes from the Bulgarian word for a fortified settlement, and the Thracian fortress on the summit explains it: a round citadel 100 m across, walled with rough stones laid without mortar, whose foundations are 2.5 m thick. In the centre stood an altar to the god Apollo Aulariok, and about 30 m from the top, rock-cut markings survive on the cliffs.

Spring and autumn offer the best conditions for hiking, with more stable weather patterns. Sturdy hiking boots with good grip are recommended for navigating the rocky and sometimes steep trails.

On clear days, the summit offers views stretching across both Bulgarian and Turkish territories, as the peak sits near the international border. This perspective reveals the geography on both sides of the boundary line.
