March 2019. Mostar, Bosnia and Herzegovina. View of downtown Mostar and the Nevertva river. Mostar, the largest city in Herzegovina, saw fierce fighting during the war between its Croat and its Muslim Bosniak communities. Like Sarajevo, it was before the war a symbol of a cosmopolitan Bosnian society where all communities cohabitated peacefully. Nowadays, it is a divided city along the border formed by the Neretva river, the Croats on one side, the Muslims on the other. Each community has its own police stations, fire stations, bus station, football team and of course its own schools and university where different versions of the same history are being taught.
