Description: Reconstruction of hypocaust in Augusta Raurica (Augst). Augusta Raurica is a large Roman archaeological site and an open-air museum in Switzerland. Located on the south bank of the Rhine river about 20 km east of Basel near the villages of Augst and Kaiseraugst, it is the oldest known Roman colony on the Rhine. A hypocaust (Latin hypocaustum) is an ancient Roman system of central heating. The word literally means "heat from below", from the Greek hypo meaning below or underneath, and kaiein, to burn or light a fire.
