The door does not reach the ground. It opens well above ground level and was reached by a wooden ladder that was hauled up from inside at the first alarm: the one detail that explains, at a stroke, what this square block of stone some 12 metres high was for. A cistern was cut inside, because an isolated garrison has to hold out on its own for a few days; outside there is a single loophole and four windows. Nothing decorative, everything functional.
The tower is what survives of a Norman lookout of the twelfth century, set on a spur that the documents first call Roccam de Principatu and that everyone now simply calls the Rocca. The Normans were not the first to take it: beneath them lie traces of a Bronze Age settlement, and alongside stand Samnite walls in polygonal masonry, blocks laid without mortar by the Pentri. A ring of walls once ran round the tower, and the medieval village attached to it stood beside it; the earthquake of 1456 damaged both.
Visiting
You walk up from the old centre of Oratino, and the climb justifies itself: seen close up, the masonry matters less than the spot it was planted on. From the top it becomes clear why the Normans chose this spur and no other — the whole valley can be watched, and anyone coming up was visible from far off. It also explains why, in the Catalogus Baronum around 1130, the local lord was called Hugo de Rocca, Hugh of the Rock, named after his own stone.
Our editors' tip
Look at the lower walls, the ones that seem to be no more than loose rubble: those are the polygonal blocks of the Samnites, and they are the most direct way to measure the centuries separating two fortifications stacked one on top of the other. Bring binoculars — from the crest the Rocca keeps an eye on the whole valley, and the village itself, one of the borghi più belli d'Italia with its tradition of stonemasonry, reads from above like a plan.
