Following the white limestone that seems to emerge from the turquoise Buna River, Blagaj Tekke is also known as the Dervish House. Built in the late 15C in an adulterated Eastern Bosnian style, this building served both as a dwelling and place of prayer. It has a hammam, guesthouse and even a room dedicated to the tombs of important Muslim dignitaries. It is one of the most interesting buildings in the country, historically and architecturally.
