At this place in Roman times there was a facility to capture groundwater and spring water, where the Romans supplied water through canals into the fortress. Then all of this was wiped out by the time. The catch-water drain had been destroyed, but remained a spring, whose water was drained out under the roots of an old hornbeam. People draw water from it and quenched their thirst, when they hoed and harvested the land.
There are many picturesque and leisurely walks and trails surrounding Momchilovtsi where you can wander and explore nature at its very best in the calm and tranquility of the forest high above the village. One such trail takes you past the small Chapel to Dupchov Kamuk - the Stone with the Cross.
