Archaeologists unearth medieval convent’s heating system during renovations in Switzerland

During recent renovations in Switzerland, archaeologists have uncovered the medieval heating system of the historical Gnadental convent. The convent, originally built outside Basel's city wall for the Franciscans around 1231, served as a temporary home for several religious orders throughout its history.

The discovery sheds light on the infrastructure of the medieval monastic site. The excavation highlights the architectural and historical evolution of the convent, which has hosted multiple orders over the centuries following its initial construction in the 13th century.
