The Ponorici wall

Imagine: 
English
Overlooking Cioclovina cave, starting from Mesteacănului hill and going along the ridge that is parallel to the Ponoriciu valley, there is a vast straight-line Dacian fortification system, consisting of an earth and stone wall, about 2.5 km long. The main wall is connected to over 30 secondary walls that were built in an oblique position, in a “fishbone” pattern, and with semi-circular strongholds from place to place. It was meant to block the access to Sarmizegetusa Regia from the Strei valley. The straight line distance between these fortifications and the fortress of Piatra Roșie is 2.5 km, but the real route is about 6 km.
