The fortress town of Vranduk is located on the river, about ten kilometers south of Zenica-Doboje. The name first appears in written sources at the beginning of the 15th century. The fortress is located in a rather beautiful place, on top of a hill, which is surrounded by the swift river Bosna. The building itself is not very large, and you can walk around it very quickly. Of the interesting things inside, there is a small old cannon on the fortress wall and an ancient well.
