Basilika St. Marcellinus und Petrus

Basilika St. Marcellinus und Petrus is a church building within the Seligenstadt Abbey complex, featuring three rounded arch portals in its western facade. The interior displays baroque design elements with decorative details and religious artworks throughout the space.

This basilica was founded in the 9th century during the Carolingian period and underwent comprehensive baroque renovation in the 18th century for the abbey's 900th anniversary. That major transformation gave the building its current appearance and character.

This basilica serves as the spiritual heart of Seligenstadt Abbey and continues to be used for regular Catholic worship. Visitors sense the deep religious significance this place holds for the local community.

The basilica is accessible through the main western staircase flanked by statues, with additional entrances available at the side portals. Visitors should note that this is an active place of worship, so access may be limited during religious services.

Inside the basilica stands an organ built by Wilbrand in 1981 featuring an extensive keyboard and pedal system. The instrument was later revised and restored by Hugo Mayer to preserve its sound and functionality.
