Holy Roman Emperor Otto I, who is entombed at Magdeburg, appointed his brother Bruno as Archbishop of Cologne. Bruno found St.Pantaleon in need of repair and began a massive renovation. He died in A.D. 965 and is buried in the crypt. In 972, Otto arranged the marriage of his son, Otto II, with Theophanu, a princess of the Byzantine Empire. After Otto’s early death, Theophanu ruled the empire as regent during the minority of her son, Otto III. She installed her daughter Adelheid as abbess at St. Serviatus, Quedlinburg. She funded the extension of the westwork of St. Pantaleon, and on her death in A.D. 991, was entombed at St. Pantaleon.
The church is a quick guide to the history of art and architecture from roman times to the present. Beneath the choir, excavations have uncovered the foundations of a roman villa dating to the 3rd century.
Later this plot of land became a cemetery and a simple chapel was raised on the site in the 7th century. In the 9th century, under Bruno, this was lengthened and remains as the nave of the church. Theophanu’s contribution was the western extension with these bi-color arches that were characteristic of 9th and 10th century Rheinland churches.
In the 12th century, side aisles with groin arches were added, a gothic rood screen followed in the early 16th century with further additions of a gothic apse, stained glass windows and a massive baroque altar (1747-9).
The central nave was vaulted in the 17th century. But after damage in WWII, it was restored as a coffered ceiling more in line with the original design. The religious symbols etched in the panels are executed in a very 20th century style.
