The Museum’s collection is mainly made up of archaeological finds from the Minho region, in particular from Bracara Augusta, covering a wide chronological period from prehistory to the Middle Ages. Here we can find vestiges of a Roman dwelling in situ, with a beautiful mosaic and a remarkable set of Roman milestones, as well as remains of a necropolis. In addition to these exhibition spaces, it has an educational service, a library, a shop, a café and a garden.

The name of the Museum is associated with Archbishop D. Diogo de Sousa (1461-1532), responsible for important urban remodelling measures in the city of Braga and the first attempts to safeguard the remains of the Roman occupation, the “Bracara Augusta”.

The Museum, which is part of the Portuguese Museum Network, is active in the preservation, valorisation and mediation of local and regional archaeological heritage. It opened its doors to the public on 29 June 2007, in a building built from scratch and located in the most significant archaeological area of ​​the Roman city of Bracara Augusta. As such, the museum is the starting point for a tour of the surrounding archaeological sites.
