The village of Radouň was called Radaun by its German residents. Today, the village is a part of Štětí. Radouň underwent a boom at the end of the 19th century when there 129 houses with 900, mostly German, residents. The village currently has 190 - 200 permanent residents. Radouň is one of the oldest villages in the Litoměřice district because the very first notion dates back to the 11th century in the establishment deed of the Litoměřice Chapter. Early in the 20th century, there was a large fishpond where the large park-style village square with its high trees stands today. On the southern side, the village of Radouň co-financed with Count Karel Hubert Pachta from Rájov (von Raihofen) based in Liběchov, the construction of the St. Florian Chapel. The charming chapel building is built in the late Baroque style and the structure was reconstructed in 1866, 1930 and finally and finely in 2005. At the village entrance from Štětí is the sculpture of St. Florian, the patron of firemen, dated 1753 (i.e. before construction of the chapel) on a high pedestal. The former brewery's cellars are a rare structural sightseeing attraction. The large cellars are located between houses 51 and 60 and under the adjacent reconstructed road. There are several semi-timbered cottages in a Lusatian style and the oldest date back to 1779 and 1808. Some houses are in the early 19th century Empire style. There are many houses in a recreational style. In the 18th century, there was a large Jewish population in Radouň. A visible relic of the Jewish settlement in Radouň is the Jewish cemetery established in 1789 on the hillside northwards from Radouň. In 2003 - 2005, the cemetery was cleared from wild plants and bushes and is now regularly chemically treated. The ceremonial hall was statically stabilised, the dome was repaired and the circumference walls were bricked up and coated with plaster. There are two deposits of protected herbs - orchis militaris. The military orchid is the Bohemian orchid growing on lime soils and dry sunny hillsides.
