To the north and south of the basilica, with connection to the underground pilgrimage of the Stollenkrypta, are the Lambertusbrunnen and the Aegidiusbrunnen (Gedd'schesbach). The construction time of these historic and water-rich wash wells is unknown. In the morning book the "Göttgensbach" was already mentioned in 1688. The source of the Lambertus well could already have been a sanctuary of the Romans.
