Vrelo Bune

Vrelo Bune is a natural and architectural ensemble located at the spring of the Buna River near Blagaj, a village-town, and is part of the wider "Townscape ensemble of the town of Blagaj — Historical and Natural Heritage of Bosnia and Herzegovina", situated southeast of Mostar, Bosnia and Herzegovina. The primary rationale behind the decision of the KONS to designate the site as protected and thus include it in the protected area of Blagaj as a historic urban area, lies in the harmonious coexistence of natural and architectural, cultural, and historical elements, as evidenced by the "distinctive quality of the coexistence of the natural and the man-made" and the "integration of the physical structure into the landscape".
