The north wing is one of the earliest buildings of the Ingelheim imperial palace and dates back to the Carolingian founding period. It consisted of a long block of buildings - the so-called north wing - and a hall building attached to it at right angles. The north wing, the remains of which can be seen here in The church had a length of about 60 metres and an interior depth of eleven metres. On the side facing the inner courtyard a portico ran along the street. The interior of the north wing was divided into six to eight rooms of varying width.
The function of the north wing has been interpreted several times as a residential wing. The individual rooms were lavishly furnished, but relevant finds, such as for example, traces of heating equipment, are still missing.
Since 2012, an archaeological window has shown a cross-section of the north wing at this location. The gravel-covered floor of the monument area lies on Height of the historical running level. In addition, two reconstructed stumps of columns illustrate the location and dimensions of the former colonnade.
