In the 19th century many finds from the Roman era were recovered in Remagen. They were initially stored and displayed in the council chamber. When an excavation in 1900 brought to light further finds, it was decided to convert a 15th‑century Gothic chapel into a museum. The small museum has the advantage that visitors can learn a great deal in a short time about life and death in a Roman auxiliary fort. All the exhibits were found in Remagen, so one can get an impression of what remains of the Roman barracks and civilian settlement that endured for three centuries, and of how modern archaeology interprets those remains.
