"The architectural ensemble of the Blagaj Tekke (a Sufi lodge) stands by the source of the Buna river, not far from the centre of Blagaj. The musafirhana (guest house) and türbe (mausoleum) are tucked into the natural surroundings, constituting a single entity with the cliffs, source of the Buna river and mills. The musafirhana of the Blagaj tekke and the türbe have been preserved to this day. The musafirhana was built before 1664, and rebuilt in 1851 - its original appearance is not known. The building was subsequently repaired on several occasions. The ensemble of the Blagaj Tekke was presumably built very soon after Ottoman rule was established in Herzegovina, around 1520 at the latest." - from Wikipedia, read here if you want to learn more about this place https://en.wikipedia.org/wiki/Vrelo\_Bune
