Golubac area is full of mineral springs such as Dobra voda (Eng. Good Water) in Klenje village.

One of the first Christian churches in the area, dedicated to Saint Dominica Martyred (Serbian: Sveta Velikomučenica Nedelja), was built here. Present church was erected on foundations of a building dating back to 13th century and remains of it can still be seen.

A legend says that a church was built on a place called Duboki potok (Eng. Deep Creek) where Roman soldiers beheaded a girl who had refused to renounce her faith, Christianity. The spring has always been considered as curative – locals believe it heals eye illnesses and general body weakness.
