Why go now: Mark 25 years of peace What to know: Partially destroyed during the Bosnian War (1992–1995), history-rich Mostar still bears scars of the past. Numerous buildings in the Old City, developed as a 15th-century Ottoman frontier town, have been rebuilt or restored in the 25 years since the Dayton Peace Accords established relative calm in the western Balkans. Wander around and you’ll pass newly renovated apartments next to buildings riddled with bullet holes. Local and international artists regularly decorate the abandoned structures with colorful murals. Mostar’s most tangible image of peace is the 16th-century Stari Most (Old Bridge), rebuilt in 2004. It connects the city’s predominantly Christian Croat west side with the mainly Muslim Bosniak east. —Barbera Bosma, managing editor, Nat Geo Travel Netherlands When to go: May How to go: Visit Mostar as part of a 12-day National Geographic Journeys “Discover the Balkans” trip, offered in partnership with G Adventures.
