Bonifatiuskloster, Catholic monastery in Hünfeld, Germany

Bonifatiuskloster is a Catholic monastery founded in 1895 in Hünfeld, designed by Paderborn cathedral architect Arnold Güldenpfennig. Its neo-Romanesque church, built 1897–1900, is a cruciform three-nave basilica with a south portal topped by a rose window, round-arched windows, pilasters and friezes, flanked by twin towers with diamond-shaped roofs. The model was a Romanesque church in Brittany.

The Oblates founded their first German house here in 1895; Arnold Güldenpfennig designed the complex, built from 1896 to 1900, and the community met in Hünfeld's town hall until 1899. The National Socialists expropriated the monastery in 1941 and expelled the Oblates, who returned in September 1946; the library, taken to Berlin, came back with help from US soldiers. The philosophical-theological college closed in 1971, after which the house became a retreat and conference centre.

The monastery is known locally as the Hünfelder Oblaten. Its church holds a relic of the Holy Cross set in a massive silver reliquary, given by Princess Anna of Hesse, who also donated liturgical vestments kept in the sacristy. The ambon is carved as a scroll with two seals: an angel touching Isaiah's lips with a burning coal, and founder Eugène de Mazenod with his companions.

The monastery is a spiritual centre receiving around thirteen thousand retreatants a year, so the church and grounds are working spaces rather than a museum. The church has a separate confessional room for confession and spiritual conversation, and the complex also holds a private chapel seating eighty people. Groups come for retreats and conferences, so check ahead whether the church is free during a session.

During World War One, the monastery served as a reserve hospital caring for wounded soldiers from the fighting. After the war ended, the building returned to its original purpose and became a place of prayer once again.
