Alt St. Heribert

Deutz Abbey was a Benedictine monastery located at Deutz, now part of Cologne as Köln-Deutz, North Rhine-Westphalia, Germany.

It was founded in 1003 on the site of a Roman fort by the future Saint Heribert, Archbishop of Cologne, close adviser of Emperor Otto III. Heribert died in 1021 and was buried in the Romanesque church he had had built here. The theologian Rupert of Deutz was abbot during the 1120s.The abbey had extensive properties, but its strategic position by the Rhine exposed it to involvement in fighting, and it was destroyed in the 14th century and again in the 16th. It was dissolved during the secularisation of the Napoleonic era, but the abbey church, now known as Alt St. Heribert, became a parish church in 1804.
