There are some seriously stunning pieces of Ottoman architecture dotted around Mostar’s old town, with the 17th century Koski Mehmed Pasha Mosque front and centre of it all. The views from the minaret are gorgeous, although be prepared to share that view with plenty of other gawping visitors. The courtyards are free to explore and well worth doing so, especially during the heat of the summer — the drinking water and shade is a godsend.
