Protected cultural monument of great significance, listed as AN 37 with the Republic Institute for the protection of monuments of cultural heritage.
The remains of the ancient fortification Timacum Minus are located in the today’s village Ravna, northeast from the village, on the left bank of Beli Timok, en route of Roman road from Nis to Ratijarija in Bulgaria (Naissus-Ratiarija). They are about 9 km north of Knjaževac, on the road towards Zaječar.
Archaeological research in Ravna village began in late 19th and early 20th century by Anton von Premerstein from Austrian Archaeological institute and Nikola Vulić, professor from the University of Belgrade. Systematic research organized by Archaeological institute from Belgrade and Homeland museum of Knjaževac begun in 1975. Fortress ramparts and parts of civilian settlement with thermal baths and necropolis were discovered.
In written sources, the fortification Timacum Minus is mentioned as early as 78, as the seat of the Roman army cohort I Tharacum -Siria, after the transfer of the unit to Moesia. A significant restoration came about in III-IV century when more towers were built and older tombstones were used for building. The last restoration happened in VI century, at the time of Justinian. The fortification represented an important link within the inner limes, fortified for the protection from barbaric intrusions.
In the central part of the fortification, a rectangular building was discovered, whose southern façade faces the north side of the main street which connects east and west (decumanus). It was built with the combination of rows of brick and stone tied with quicklime mortar – a technique known as mixtum. The building had an upper floor supported by columns that also fortified the walls of the ground floor. Although it was originally believed to be a granary, it is possible that the building was in fact a principia, the seat of administrative-military authority of the castrum Timacum Minus in the IV century.
In the northeast corner of the fortification, a circular edifice was discovered, with a pool in the middle, 6 m in diameter. It was built with stone and mortar, with waterproof mortar on the floor. The analyses of samples from the object point out that ore flotation was performed here as well as separation of silver and gold.
The southern gate of the fortification is largely preserved. It has a special building technique, as it was partly built with large stone blocks of sandstone, in drywall technique (without binding material), which points out to the work of local craftsmen. The gate was protected by rectangular towers.
Thermal baths were discovered outside the walls of the fortification, to the northeast, next to the bank of Beli Timok. On the east side of the building there is changing room - apodyterium, in the continuation is the tepidarium, room with lukewarm water. On the other side, there are two rooms with hot water– caldaria, connected to the firebox – praefurnium. On the south side there is a pool with cold water– frigidarium. Thermal baths were built with crushed stone and pebbles and were used while the fortification was in function.
West from the fortification, on the Slog locality, a part of late antique necropolis was discovered and researched. In the late III and early IV century the deceased were buried both by cremation and burial.
In the layer above the antique one, the remains of a Slavic necropolis were discovered, from IX-X century, judging by the way of burial.
The research of necropoli indicated the beliefs of the peoples, as well as the changes in social and economic status of the community.
