The actual medieval fortress on top of Visočica hill — the kind the modern pyramid theorists tend to ignore. What survives is mostly the outline of the curtain wall, a ruined tower, and the foundations of the king's hall, but the position is unambiguous: a natural acropolis with views over the entire valley.
Reached on the same path as the pyramid excavations. There is no entrance fee at the top; the site is unfenced and unmanned.
