The Angustia camp is located at north-east of Bretcu village, Covasna county, before the Oituz Step. It is easily recognizable in the field by the very prominent wave of land enclosing a quadrangle. The first excavations were made in the year 1877 inside the camp. In that year it was discovered the “via principalis”- the main building of the camp.
The first systematic researches have been undertaken only between the years 1925 – 1926 of Emil Panaitescu. In this period were discovered the camp baths at 100 meters from the camp. The stamps from the bricks located in the camp and baths belong to the military units CHO(ors) HIS(panorum) and CHO(ors) I BRAC (araugustanorum).
In 1950 a team led by M. Macrea have carried out new excavations. On the large terrace called “Wolf’s City”, were discovered, on a surface area of 2-3 hectares, fragments of bricks, tiles and ceramics, indicating the place of the civil settlement located near the camp.
On the territory of the camp were discovered many coins: an Dacian imitation of silver after a drachma of Alexandru Macedon, a Republican denarius, an imperial denarius from Vespasian and one of Traian’s. In 1547 it was discovered a military diploma made of bronze, dated in June 14, year 92, belonging to a soldier of the Roman fleet from the Danube, Classis Flavia Moesica.
In the output of Oituz Step, on the left side of National Road, it was found a Roman watchtower of a quadrilateral shape. Inside the tower were found bricks with the stamp of the military units Cohors I Hispanorum and Cohors I Bracaraugustanorum.
In May 2010 the Frankfurt Institute of Archaeology and National Museum of Eastern Carpathians have conducted some investigations with modern instruments, scanning the entire perimeter of the camp.
