Schlosskirche

The Catholic Church of St. Nicholas was already mentioned at the end of the 13th century as a chapel. In 1437, the inhabitants of Buchhorn enlarged the chapel into a Gothic church and erected the tower which is still recognisable today. After the destruction of the monastery in Hofen during the Thirty Years' War, the citizens made St. Nicholas' Church their parish church. In 1689 it was extended and modified. According to the taste of the time, the Gothic vaults had to give way to a flat ceiling. In the 18th century, the church tower was given its present form.

The Catholic Church of St. Petrus Canisius was built between 1927 and 1928 according to a design by Hugo Schlösser and Wilhelm Friedrich Laur. In 1938, the church was raised to the status of an independent parish church. The structure is an ostentatious three-nave basilica in the expressionist architectural style.

Salem Abbey, founded in 1136, was one of the most important Cistercian monasteries in Germany. The abbey soon became very prosperous, with large and magnificent structures erected in three different courtyards and a splendid church built between 1182 and 1311. Other foundations such as Raitenhauslach Abbey (1143), Wettingen Abbey or Stella Maris (1227) and Königsbronn Abbey (1303) were founded from this abbey. A fire in 1697 almost completely destroyed the abbey, which was immediately rebuilt in the baroque style. In 1803, the monastery was abolished and the buildings were used by the Grand Dukes of Baden, who united them in the Salem Castle complex.
