Blagaj's signature attraction is this pretty half-timbered Dervish House standing beside the surreally blue-green Buna River where it gushes out of a cliff-cave. Upstairs the Tekija's wobbly wooden interior has some attractive woodwork and a fine ceiling in the Firdevs room.
The complex is thought to have been founded in the early 16th century, According to one legend it was built as a thank you to the dervish whose St-George-style dragon slaying rescued the daughter of Duke Stepan. Recently restored, the complex is still a venue for Zikr praise-chanting three nights weekly. The inscriptions (in Arabic) 'hu' that you'll see throughout the site mean 'Him', a term for Allah intoned in such chants. The best views of the complex are from across the river on the upper level of the Vrelo Restaurant.
