Breg (in Slovenian pronounced as /ˈbɾeːk/) is a settlement in the hills south of Mežica in the Carinthia region in northern Slovenia.[2]
It was a typical miners' settlement associated with the nearby lead and zinc mine under Mount Peca. As such, the entire late-19th century miners' village has been declared a monument of national heritage by the Slovenian Ministry of Culture.[3]
