Due to the disruptions caused by the Napoleonic invasion, custodianship over the abbey's assets and property was granted to the Princely House of Thurn und Taxis for the years 1803-06.

Abbot Amandus Fischer (1711–29) had brought in architect Dominikus Zimmermann to rebuild and redecorate the abbey's Festsaal, which was carried out in 1719-20 in a high Rococo style.

Neumann's plan called for a conventional basilica consisting of nave, crossing and choir which were articulated as a series of oval-shaped bays surmounted with shallow domes.

Subsequent architects altered or abandoned the original design, particularly the construction and profile of the domes, which slowed progress.

Johann Nepomuk Holzhey of Ottobeuren built the last of the great South-German, Baroque organs at Neresheim between the years 1792 and 1797.

In 2004, the monastery set up the Neresheim Abbey Boys' Choir, which provides a free musical education and voice training.

The choir sings regularly at services in the abbey church at Neresheim and also makes appearances outside the monastery.
