The bridge rises over Sarnena river (Karadja dere), about 1.8 km from Lyubcha village on the route of an old roman road. Based on anecdotal data and historical researches, eggs were used for a better solder of the stones when building the bridge. Some scientists claim that the roman road and the bridge were built around II-III century.
Most of the old stone bridges in the Rhodope are built on the road network of the Roman empire, which is why they are called “roman”, but in actual fact they date back form the late Medieval period.
In 2007 an initiative of the local municipality the bridge was fortified after treasure hunters started digging its basis. The area is known for its numerous archeological findings, and the village is famous as the only location in Bulgaria where the symbol of Egypt – the Scarabeus beattle was found and is now kept in the Smolyan museum. The stone is part of an amber necklace, found during archeological research back in 1976 in a mound dated VII-VI century in the area known as Bardzeto near Lyubcha village. The world famous Bulgarian scientist Egyptologist dr. Vassil Dobrev, which works in Cairo, has managed to read the name of the pharaoh from the eleventh dynasty encrypted on this unique stone in the shape of the sacred scarabeus.
