There was indeed a Roman camp in Castres in Antiquity, but it was especially in the Middle Ages that the town began to take shape. The colourful houses, linked to the textile activity – formerly the homes and workshops of tanners, weavers or dyers – are still lively witnesses.
Built along the Agout river, Castres develops around Saint-Benoit Abbey, which will become Episcopal Palace before becoming City Hall / Goya Museum. Throughout history, Castres has not stopped developping.
