In addition to the great hall, the chapel was an important building for official gatherings and high ecclesiastical feasts. Because the high clergy were usually the only ones who could read and write, they monopolized the administration. For the same reason a cleric functioned as Chancellor at the Imperial Court. An additional private round chapel stood next to the Imperial apartment.

The excavated foundations of the chapel at Werla are comparable to the still existing ruins at Walbeck / Aller (built in the middle of the tenth century). When the fortifications deteriorated, the church became the center of a village consisting of nearly twenty timber-framed houses.
