Bracara Augusta had a civil and administrative origin. It was founded to stabilise the indigenous populations and to facilitate their urban integration. As the headquarters of the judicial conventus, it could administer justice, collect taxes, recruit troops and organize the Imperial cult.
The population was mostly indigenous though it had since the beginning attracted Roman citizens namely craftsmen and administrative agents, as well as the military. The latter were responsible for urban planning, the infra-structure of the water supply and sewage and the network of roads.

The city was organized along orthogonal lines defined by the two main axis of internal circulation – the cardus (NW-SE) and the decumanus (SW-NE). The other streets had the same orientation and they formed square insulae with an area of 150 ft between the axis of the streets.
Bracara Augusta
A characteristic element of the urbanization of Bracara Augusta was the porticos, which ran along the side of the streets and functioned as footpaths or as extensions to the shops (tabernae).
There is no indication that Bracara Augusta had a wall surrounding it when it was first constructed, it was rather an open city.
In terms of urbanism by the end of the 1st century, beginning of the 2nd the city reached its maximum size. It then underwent a significant urban renewal. The end of the 3rd century – beginning of the 4th was marked by great renewal, probably because the city became the capital of the province of Galecia.
The biggest construction of this era was the surrounding wall similar to the ones in other provinces, which probably followed a plan for military defence of the Western Roman Empire.
