History
The tower most likely traces back to a chapel mentioned alongside Deutz Abbey in a document from 1147. As a dependent chapel it belonged to the parish of Urbach until Heumar gained its own parish in 1698. The nave was declared structurally unsound in 1824 and demolished after 1826; the replacement church, Neu St. Cornelius zu Rath/Heumar, was completed in 1834.
The Tower
Toward the end of the 19th century, art historian Paul Clemen was still able to examine the tufa stonework in its unaltered state. On the then-open east face he identified limestone string-courses marking two earlier rooflines — one spanning the full width of the tower, and a later one belonging to a larger structure that extended northward.
Later Changes
In 1927 an apse was added to the east side so that the ground-floor space could serve as a chapel and memorial. A renovation in 1968 reversed this: the apse was removed, the east wall was closed up, and the entire tufa masonry was replaced in the process. All traces of the earlier rooflines and the evidence for the former nave were lost.
