There are various sights in the town itself and in each of the villages. There are many well-preserved half-timbered houses in the old town centre, such as the Miners' Guild Hall dating from 1898, and in the village of Wesseln. The Catholic Church of St. Gallus at Detfurth was built in a classicist style in the period 1772 to 1779. Other interesting village churches and chapels can be seen in Hockeln,
Bodenburg, Breinum,
Östrum, Wehrstedt and
Klein Düngen. The Church of St. John the Baptist in
Wesseln was built in a typical
neogothic style in 1853-55. The largest church in Bad Salzdetfurth itself is St. George's Church, a Protestant church with a painted wooden ceiling, which was built around 1700. In the west wall a mark, which is 3 metres above ground level, indicates the height of the flood waters of the River Lamme in 1738. The
baroque altar dates from 1717. The organ, dating from 1590, originally stood in
St. Lamberti, Hildesheim. There is a municipal museum dedicated to the mining history of Bad Salzdetfurth. Originally the brick building which now houses the museum was a school. The museum was founded in 1987. The most modern church in Bad Salzdetfurth is the Catholic
Holy Family Church which was built 1960-61 and consecrated on 3 September 1961. Its organ dates from 1979. Originally, very few Catholics lived in Bad Salzdetfurth. After the Second World War, however, many Catholic refugees from
Silesia settled in the town. == Traffic connections ==
