St. Bonifatius, Catholic church in Hessisch Oldendorf, Germany

St. Bonifatius is a Catholic church at Schilfstraße 18 in Hessisch Oldendorf, built in 1950 to plans by Fritz Schaller. A tall square white tower with a steep brown pyramidal roof and cross stands beside a long white-walled nave with a dark brown tiled roof and a small arched porch. The interior is white, with a crucifix above the altar and 14 Stations of the Cross on the side walls.

The church was built in 1950 following the establishment of a Catholic community in 1944 among displaced persons during World War II. This construction reflected broader demographic changes in the region triggered by wartime displacement.

The church serves as a gathering place where parishioners meet regularly for worship and celebrations that shape community life. The Boni-Max carnival demonstrates how the local Catholic community has developed its own way of marking the year together.

The church is at Schilfstraße 18, not 18a; the neighbouring parish house is at number 16. It is a filial church of the parish of St. Sturmius in Rinteln, in the Weserbergland deanery of the Diocese of Hildesheim. The entrance is through a covered portal on the north side.

The ground floor of the free-standing bell tower holds a memorial with a row of plaques. They name the dead from Knispel, Tschirmkau, Zauchwitz and Zinnatal in Upper Silesia who died in the Second World War, while fleeing, or in Polish and Soviet camps. A plaque also honours the church's builder, Pfarrer Max Czerwensky.
