Roman thermae of Clunia, Roman bathhouse in Coruña del Conde and Peñalba de Castro, Province of Burgos, Spain

The Roman thermae of Clunia are ruins of a bathhouse with separate chambers for cold, warm, and hot baths. An underground heating system with channels connected the different sections together.

This bathhouse was built in the first century when Clunia was an important administrative center in Hispania. The structure reflects how advanced Roman infrastructure had become by that time.

The baths were central to daily life, where people gathered not only to wash but also to socialize and discuss local matters. These spaces reveal how important communal bathing was to Roman society in this region.

The two bath buildings, Los Arcos I and Los Arcos II, are separated by a porticoed street; visitors walk between them along the excavated area. Excavations are still ongoing, so some sectors may be fenced off. The site lies between Coruña del Conde and Peñalba de Castro, in the south of the province of Burgos.

In the 5th century the baths stopped being used for bathing, and part of the complex may have housed a workshop making Hispano-Roman terra sigillata pottery, as shown by the many moulds found there.
