Onze Lieve Vrouw van de Allerheiligste Rozenkrans

The oldest church in Buchten dates from the 13th century and was built in Romanesque style. The parish itself was much older. This church fell into such disrepair at the end of the 18th and beginning of the 19th century that replacement was deemed necessary. In several phases between 1833 and 1837, a new brick church was built in neoclassical style to a design by architect/contractor Beugels from Oirsbeek. The 13th-century Romanesque tower was preserved.

Three-aisled nave, single choir and west tower, 1843. Outer section with round-arched recesses. Nave and choir with stucco barrel vault. Flat-roofed side aisles. Round arches on Tuscan columns. Confessional, 1809. Baptismal font from around 1200. Single-manual organ, made in 1857 by M. van Dinter and L. Vermeulen. Two oak lord's benches. 18th century? Bell tower with chime consisting of a bell by J. Sulris, 1529, diam. 126 cm and a bell by J. van Venrade, 1478, diam. 90 cm.

Neo-Romanesque church with large tower placed on the side. Characteristic Boosten church. The medieval chapel (later church) of Dieteren was first mentioned at the beginning of the 16th century. It stood at the cemetery, on the current northern exit road, towards Echt. This church was demolished at the beginning of the forties of the 1800s. In 1835, Dieteren was separated from the mother parish of Susteren and elevated to an independent parish. That is why a new, larger church was built on the same site around 1845, in a transitional style between classicism and neo-Gothic. Due to its dilapidated state, a new neo-Romanesque church was built in the centre of the village from 1938 to 1940, designed by architect Alphons Boosten from Maastricht. The main entrance is on Kerkstraat and the nave is separated from Vleutstraat by a narrow garden, which is used as a fairground on public holidays. In 1940 the new church was consecrated by the bishop, after which the church from 1845 was demolished.
