In the center of Bela Palanka is a well-preserved mile marker, a kilometer reader dating from the beginning of the third century AD. The stone column is 2.4 m high and is well preserved. 

Milestones are the rarest archaeological discovery, because they were relatively few and were usually placed at crossroads or places where travelers replaced tired horses. It was erected in 230 AD on the main Roman military road Via Militaris during the reign of Emperor Alexander Severus, the last emperor from the Severus dynasty that ruled Rome for 42 years. The map shows the distance from Niš to 22 miles, or 35 km, which coincides with the current distance of that place from Niš.
