Ara Ubiorum, Roman sanctuary and archaeological site in Cologne, Germany.
The Ara Ubiorum stands as a federal altar from Roman times, positioned within the ancient boundaries of Colonia Claudia Ara Agrippinensium in present-day Cologne.
Built during the last decade of the 1st century BC, this altar served as a central worship location for Germanic tribes under Roman control.
The altar employed German priests from noble families to maintain the sanctuary, creating connections between local leadership and Roman administration.
Archaeological excavations near Old St. Alban's and Gürzenich areas of Cologne reveal foundations and structures related to this ancient Roman sanctuary.
A Cherusci prince named Segimundus abandoned his priestly duties at this altar upon learning about the Roman defeat in the Teutoburg Forest.
