Founded in 1881, the Martins Sarmento Society is a vital cultural institution in the study of Celtic culture. It was named after Martins Sarmento, the archaeologist who led the excavation of the Citânia de Briteiros in 1875.
This archeological museum can be found within the cloisters of the Martins Sarmento Society headquarters, the Igreja de São Domingos.
Several truly impressive artefacts can be found here, including Roman milestones, thick columns, and an ancient Celtic sarcophagus covered in moss.
There is also a stunning display of pedras formosas (beautiful stones) which were once used to decorate the Celtiberian bathhouses.
Also, check out the intriguing case of Neolithic and Paleolithic tools and the bizarre miniature bronze chariot.
