In St. Peter, one can not only admire artistic treasures from past centuries but also discover contemporary craftsmanship: The colorful interior painting is by the Bavarian painter Karl Manninger and his student Hermenegild Peiker. The historical model for this work were the frescoes by Joseph Appiani (1752–1755), which were destroyed in the war. The extensive paintings depict the life and legends of the Apostle Peter; an original fresco is still preserved behind the entrance.
The church was founded in 944 by Archbishop Friedrich of Lorraine. In 1748, court architect Johann Valentin Thomann built the current new structure on the site of the demolished parish church of St. Marien. The original late Baroque elegance was largely preserved during the historical restoration. Particularly noteworthy are the richly decorated white and gold wooden pulpit from the workshop of Johann Förster and several elaborately designed altars, including the cross altar by court sculptor Hans Backoffen from the 16th century.
The celebration altar dates from 1989 and was created by the Palatine sculptor Gernot Rumpf – featuring his bronze “fish people” that are wriggling in a net. Later, the Ambo and the Easter candle holder were added to complete the ensemble.
