The Roman camp of Aquis Querquennis is located in Porto Quintela, in the municipality of Bande. Nowadays it is flooded part of the year by the waters of the As Conchas dam. It was declared a Site of Cultural Interest.

The place was known among the people of the municipality as A Cidá and several researchers had focused their attention on the area for some time. However, it was only with the beginning of the campaigns in 1975 that two different archaeological sites of high historical interest were finally identified: the Roman military camp and the Mansio of the Via Romana.

This Roman military settlement is related to the construction of Via XVIII, or Via Nova, which linked Braga to Astorga. Thus, acting as a strategic and control point of the road in the first and second centuries of our era.

The military enclosure has a rectangular shape and rounded corners, occupying the entire area of more than two hectares. Archaeological campaigns carried out over the decades led to the rescue of several buildings: the headquarters (principia), two granaries or barns (horrea), a hospital (valetudinarium) and five barracks for troops (strigia). In addition to these buildings, drainage channels, latrines, a perimeter road (via sagularis) and a defensive system that combines ditches and stone walls are visible.

Close to the camp is the Mansio, halfway between the military settlement and the thermal area of O Baño. This is considered one of the largest mansions in the entire Via Nova. Today you can see the remains of a courtyard with a wall and a central cistern; a corral with an oven and several divisions of a building with channels in the floor, fireplace and entrance door.
