Devil's Bridge

Devil's Bridge (Дяволският мост, Dyavolskiyat most) is a Natural Monument protected area in the Eastern Rhodope Mountains, Kardzhali Province, southern Bulgaria. The natural monument designation protects the dramatic Arda River canyon section at the village of Dyavolski Most (Devil's Bridge village), where the medieval stone bridge of the same name—considered one of Bulgaria's most impressive medieval bridges—spans the Arda Gorge amid a landscape of volcanic tuffs and rocky outcrops. The site combines exceptional geological and archaeological heritage, significant biodiversity as part of the Lower Arda Important Bird Area, and a preserved medieval engineering masterpiece.
