Kosmaj

Kosmaj is a mountain south of Belgrade [1]. In Roman period, Kosmaj was an important mining center, but today the mining activities ceased completely [1]. Evidence suggests that the iron ore was extracted even in the pre-Roman period [1]. In July 2000, during the excavations for the new sports complex in Babe, a spring was discovered in the valley of the Pruten creek [1]. Moreover, during the excavation, a hidden entry into the vast complex of Roman mines was discovered, too, being obscured for centuries [1].
