In 1377 the first cathedral was demolished and the so-called Alte Dom or Old Cathedral (e) was built, as a replacement for the first cathedral, which had been used as a choir by the chapter of the Old (Ludgerus) cathedral.
Like the modern cathedral, the Alte Dom was built in the gothic style.

In 1390, the Marienkapelle (W), Annenkapelle (Y) and Elisabethkapelle (Z) were built – the latter two were incorporated into the new sacristry in 1885.
Between 1390 and 1395, the cloisters (U) were built.
In the process, part of the Alte Dom built shortly beforehand must have been demolished and moved to the west.
Thereafter the Alte Dom was flanked by the west transept and the western end of the cloisters until its demolition in 1875.
