Sostra

Sostra is a well-preserved roadside complex located on one of the most important military roads in the Roman provinces of the Balkan Peninsula - the road "Escus - Philippopolis". It is the sixth way station located along the ancient road, which, passing through the Hemus Mountains, connected the province of Lower Mysia with Thrace. Road stations, settlements, fortifications and observation posts were built along its route, and military units with a security function were stationed there. Sostra is located in the valley of the Osam River, near the village of Lomets.
