Caldes de Montbui

The hot springs have been exploited since Roman times, and the remnants of the Roman baths and other Roman buildings can still be seen. The source of la Font del Lleó ("Lion Springs") in the main square emerges at more than 70 °C (158 °F). The town conserves parts of its medieval fortifications and the Torre de la Presó (prison). The hermitage of la Mare de Déu del Remei dates from the sixteenth century, as does the church of Santa Maria with its baroque entrance. The Roman church of Sant Sebastià de Montmajor, in the village of the same name at the extreme north-west of the municipality, is particularly well preserved.

The artist Manolo Hugué lived and worked in Caldes de Montbui, and his house has been converted into a museum displaying both his works and those of other artists. The town also has an archeological museum and the Delger museum of furniture, paintings and sculptures.

Continuing in this artistic tradition is the master landscape painter Ramon Vilanova, a native son of the city and lifetime resident.
