Herzegovina's sunniest city — old town platans, Župa vineyards, and stone bridges
Trebinje is the southernmost city in Bosnia and Herzegovina and one of the most livable old towns in the western Balkans — a compact Ottoman-era old town (Stari Grad) enclosed within fortified walls, shaded by centuries-old plane trees along the Trebišnjica River, and surrounded by the Župa valley's vineyards producing Vranac and Žilavka wines. The Arslanagić Bridge (1574) is one of the oldest Ottoman bridges in Bosnia, and the hilltop Hercegovačka Gračanica monastery commands views over the entire valley.
Trebinje has been continuously inhabited since at least the 9th century when the medieval state of Travunia was centered here — the city changed hands between Serbian, Bosnian, and Ottoman powers before becoming a firmly Ottoman stronghold by the 15th century. The Stari Grad walls and hammam were built under Ottoman rule, while the Arslanagić Bridge was constructed in 1574 by order of a local bey and later moved stone-by-stone to its present location upstream when a hydroelectric dam flooded the original site in the 1960s.
