Mostar is a city and the administrative center of Herzegovina-Neretva Canton of the Federation of Bosnia and Herzegovina, an entity of Bosnia and Herzegovina, and the historical capital of Herzegovina. Mostar is situated on the Neretva River and is the fifth-largest city in the country. Mostar was named after the bridge keepers (mostari) who in medieval times guarded the Stari Most (Old Bridge) over the Neretva.

Mostar can be visited year-round, but the best months to visit are April through October. Spring and autumn have pleasant daytime temperatures but there is almost a 50/50 chance it will rain on any given day.

The Stari Most should be the most obvious place to visit in Mostar. The Old Bridge, a UNESCO World Heritage Site, built by the Ottomans in the 16th century, is one of Bosnia and Herzegovina’s most visited landmarks and is considered an exemplary piece of Islamic architecture in the Balkans.

There is more to Mostar than just a beautiful, fairytale bridge. The stone streets of the Old Town are almost as charming as the bridge itself. The Old Town is small. With just a few cobblestoned lanes on either side of the Neretva River, it doesn’t take long at all to walk the entire Old Town. On these streets are cafes and souvenir shops.

Completed in 1618, The Koski Mehmed Pasha Mosque is the second-largest mosque in Mostar. Like Stari Most, this mosque was almost completely destroyed in the Croat-Bosniak conflict but has since been rebuilt. For a small fee, you can tour the mosque and climb the minaret for an unforgettable view of Stari Most.

The living culture is as impressive as the stories of war surrounding it, making Mostar the perfect destination for travelers seeking some authenticity.
