The source of the river Buna is one of the largest and, certainly, one of the most beautiful in Europe, and it’s one of the finest examples of karst groundwater areas. Water flows out of the 200 meters tall cliff and with its tremendous volume alone forms the river Buna. The Tekija, built at the source of the river Buna, was constructed in the 16th century for the Dervish order, and today it’s the most intricate place in Bosnia and Herzegovina. The Tekija is opened to visitors throughout the year, and in a beautiful garden you can overlook the source of the river Buna and have a refreshing drink, Turkish coffee or tea.
