On the bank of the Beli Timok River near the village of Ravna, the remains of Timacum Minus preserve a layered story of military occupation, mining and settlement in eastern Serbia. The fort lies roughly eight to ten kilometres from Knjaževac, according to the local museum and the Serbian Institute of Archaeology. Its position connected routes toward the Danube and Morava valleys and further toward the Adriatic and Aegean, while mineral deposits in the nearby Stara Planina helped shape the local economy.
The Knjaževac Homeland Museum identifies Timacum Minus as the oldest military fortification in the Timok region. Archaeological evidence places the first military installation in the mid-to-late first century AD. The Institute of Archaeology describes the site as an administrative center for a Roman mining district, active from the middle of the first century to the middle of the fifth. These dates refer to the fort’s documented Roman phases, not to the entire history of occupation in the surrounding valley.
