Remains of a Thracian fortress (on Kamuka Hill) can be seen south of Rahovets.
The fortress wall is 350 m long, and in its centre there are remains of a Thracian sanctuarya 2 m square cut into the rock and 0.5 m deep.
Downwards follows a small cave.
An interesting phenomenon has been observed on the site of the Thracian sanctuary: during the summer, the overheated limestone causes a powerful upward air stream, which disperses the stormy and thunderous clouds sideways.
That is why when there is a hailstorm, it falls onto the northern slopes of Kamuka Hill, but not on the southeastern, where the vineyards were and where the settlement itself had been built.
