Mostar’s old town isn’t the largest in Bosnia and Herzegovina but it packs plenty of punch, helped no end by a ‘small but perfectly formed’ aesthetic that is held together the country’s most remarkable bridge. The old part of the city is essentially three cobblestone streets, each lined with old stores, restaurants and cafes that open throughout the day. It can be quite difficult walking on the cobbles during summer, but watch your step and you’ll be more than fine. This is where most of the major tourist action takes place in the city.
