Samouil's Fortress
Самуилова крепост
Worth a detour
The valley between Belasitsa and Ograzhden is narrow, and in July 1014 Samuil blocked it. Basil II got a force over the shoulder of the mountain, took the barricade from behind, and the Bulgarian army was destroyed — after which, the Byzantine chroniclers say, the prisoners were blinded and sent home. The park-museum dates from 1982 and is frankly a monument as much as a museum; the ground it stands on is the point.
Story
Background
Kleidion means 'the key', and so does Klyuch, the village down the road. The pass it names is the gap where the Strumeshnitsa cuts between Belasitsa and Ograzhden — the obvious route from the Struma valley into Macedonia, and therefore the route Basil II had to take. Samuil fortified it. On 29 July 1014 a Byzantine detachment climbed round the position and came down on the defenders from above, and the Bulgarian line broke.
What happened next is the part everyone in Bulgaria knows. The chroniclers record that Basil had the captured soldiers blinded, one man in a hundred left with a single eye to lead the rest home, and that Samuil died within months of seeing them arrive. Modern historians are sceptical about the arithmetic — fourteen or fifteen thousand is a chronicler's number rather than a count — but the empire did not recover from the campaign, and it was absorbed into Byzantium four years later.
The site was laid out as a national park-museum in 1982, in the confident monumental style of that decade: a bronze Samuil, an exhibition building, a visitor centre. It is about sixteen kilometres west of Petrich on the road towards the Zlatarevo crossing. Go for the landscape as much as the display — from up here you can read the ground, and see why an army would have chosen to stand in this particular gap.
What this kind of place is
Archaeological site
A place where material remains have been recorded. In Bulgaria that can mean anything from a scatter of Roman pottery in a ploughed field to a walled city under excavation. Unless a site has a ticket office, assume there is no sign, no path and no shade.
