The Koski Mehmed Pasha Mosque in Mostar is an extraordinary example of Ottoman architecture in Bosnia and Herzegovina. Built in 1618/19, it showcases classical Ottoman design. Its founder, Mehmed Koskija, was a chronicler of the great vizier Lala Mehmed Sokolovic.
The mosque has a one-space floor plan with a dome, built from precisely tanned stone blocks. It bears a resemblance to the Karadzoz Beg Mosque but has a slightly lower minaret without stalactite decoration. Situated on the cliffs of the Neretva River in the city center, it features a porch with three domes and a beautifully crafted mihrab and mimbar.
