A visit to Mostar is all about the famous UNESCO World Heritage-listed Stari Most bridge. The bridge itself looks like something straight from Naboo in Star Wars with its beautiful sweeping arch held high by the two cylinder towers and with its setting as the focal point of the town surrounded by the Herzegovina mountains.
Despite being part-destroyed by the bombing in the 1990 Civil War, they have done a superb job of repairing it and you can still get a great feeling of its history that stretches all the way back to 1474 and the first arch that was added by the Ottoman Sultan Suleiman the Magnificent in 1557.
Sitting by the river having lunch overlooking the bridge is beautiful, and when combined with a wander through the nearby Old Town, very much justifies the 2.5 hour / 3.5hour trip from Sarajevo / Dubrovnik.
