Sievershausen has a long history and tradition in forestry in Solling, but also in poaching. Unusually for a 1200-person village, the place has two other districts in addition to the core village: the Abbecke settlement high up on the edges of the Sollingwald and the Friedrichshausen manor, the ancestral seat of the von Garmissen family. In the town center there is a large information board and a memorial stone for the "reunification" with the East German partner village Stegelitz from 1991. The St. Trinity Church is located away from the town center on the Försterweg in Sievershausen. The nave and the choir supported by buttresses were built from 1542 to 1577 from unplastered quarry stones. In 1871-72, Conrad Wilhelm Hase expanded the hall church into a neo-Gothic Kreuzkirche. According to the large stone in front of the building, the most recent renovations date back to 1966 and 2011. The school building is again in the center of the village, which, due to the tower with tower clock, is easily mistaken for a sacred building. The building dates back to 1911/12 and was built by Baurat Mattei in the local style. In front of the building there is a memorial grove for the Sievershausen victims of the world wars.
