Obermumpf

It is likely that there was a Hallstatt culture settlement near Obermumpf, though the exact site has not been discovered. Near the village church the ruins of a Roman era farm were discovered. On the outskirts of the village, several Alamanni tombs were also found. The modern municipality of Obermumpf is first mentioned around 1302-04 as Obermumphier. Until 1797 it was part of the Austrian Habsburgs district of Rheinfelden. After the Act of Mediation in 1803, the entire Fricktal, including Obermumpf, went to the newly formed Canton of Aargau. The low justice right was held by the manor house Stein, which was owned by Säckingen Abbey. Later those rights transferred to the Austrians.
The Church of St. Peter and Paul, whose patronage rights originally belonged to the collegiate church of Säckingen, has a tower from 1494 and a nave from 1738. The original church, from the 8th Century, was built on the foundations of a Roman estate. Since 1889 it has been the center of the Christian Catholic parish of Obermumpf-Wallbach. In 1893-94 a catholic church was constructed, and was rebuilt in 1962.
