Basilica of Sts. Peter and Paul, Dillingen, Baroque basilica in Dillingen an der Donau, Germany

The Basilica of Sts. Peter and Paul is a hall church built from 1619 to 1628 by court architect Hans Alberthal on foundations of 13th- and 15th-century predecessors. It measures 54.8 metres long, 22.3 metres high and 22 metres wide. The Gothic tower, raised to 49 metres in 1669 by David Mozart, great-great-grandfather of Wolfgang Amadeus Mozart, stands beside the nave.

Construction of the current structure began in 1619 under court architect Hans Alberthal, replacing earlier churches that stood on the site since medieval times. The tower was added in 1669, completing the church's visual form that remains today.

The organ was built in 1978 by Hubert Sandtner of Dillingen, reusing stops from an 1889 Steinmeyer instrument; in 2006 it was enlarged to 53 stops on three manuals and pedal. Its 2006 additions include a Cymbelstern and a Cucculus, and an electronic setter with eight thousand combinations.

The basilica is centrally located in Dillingen and easily accessible on foot from the town center. Visitors should plan around regular religious services, as access may be limited during ceremonies and special liturgical events.
