In the 1960s, during excavation activities for the foundations of the community center in the village of Kralev Dol, were found remains of a Roman villa (Villa Rustica) of II-IV C. The foundations of the villa were restored and can still be seen in the center of the village. Today the finds from the excavations are exhibited in the Historical Museum of Pernik.
According to the plan the villa is rectangular, elongated in the northeast-southwest direction. There are four wings that surround a large quad yard. Its external dimensions are: Length 65 m and width 42.5 m. The south and the west wings are fully preserved, unlike the north and the east wings who are only partly conserved.
One of the reasons for the occurrence of the villa in this place is the proximity of the main Roman road connecting Serdika with Macedonia and the Aegean Sea.
