St. Peter's and St. Paul's Catholic Church stands in the Old Town's northwest. A “Saint Peter’s Church” ("St. Peter Kirche") in Camberg had its first documentary mention in 1156. The oldest part of today's church is the tower built in 1580. After the nave collapsed in the 18th century, a new church had to be built. It was built by the Dillenburg building inspector Johann Friedrich Sckell in the "Zopfstil" (a late Rococo and early Classicism development), and is therefore one of the few examples of this building style in the region. The Electorate of Trier Auxiliary Bishop Johannes Maria von Herbain consecrated this church on 15 July 1781 in honour of the Apostles Peter and Paul.
