Built in 1452, Mostar is full of Ottoman-era style. It is famous for a stone arch bridge. The old bridge is 427 years old and spans the beautiful Neletwa River. It is one of the most famous attractions in BiH and even the Balkans and is listed as a World Heritage Site. Unfortunately, it was destroyed in the 1993 inter-ethnic war. The current stone bridge is later reconstructed. The bridge is paved with cobblestones, which is a bit slippery. Tourists should pay special attention to safety. There is a local young man diving performance on the bridge. The ancient city is full of local craft shops and local ethnic gourmet shops, and the aroma of local cuisine is occasionally floating. There are still bullet marks on the buildings of the ancient city, recording the cruelty of the war at that time, and awakening people to cherish the hard-won peace life. How important is the exchange, tolerance and mutual learning of human civilizations.
