Altes Primarius-Pfarrhaus und Superintendentur Zellerfeld, building in Clausthal-Zellerfeld, Germany

The Altes Primarius-Pfarrhaus und Superintendentur Zellerfeld is a two-storey parsonage built in 1673/74, partly solid masonry on the ground floor and timber-framed above, with exterior cladding and a converted attic under a gabled roof with a dormer added in 1909/10. Inside, an 18th-century Rococo staircase with rocaille work survives. A two-storey timber-framed stable-store with exterior cladding stands at the rear of the plot.

Built in 1673/74 after a fire destroyed Zellerfeld in 1672, the house served as the official residence of Zellerfeld's Primariuspfarrer until 1874 and as the seat of the superintendent until the office was abolished in 1871. The church administration sold the property in 1876, after which it passed through several owners. The rear Stallspeicher, added around 1765, was converted into a painter's workshop in 1903 and later into a joiner's workshop with a journeyman's flat.

The parsonage and the St.-Salvatoris-Kirche opposite, with the old school next door, formed Zellerfeld's spiritual and cultural centre on the south side of the church square. In August Reimerding's baroque grid plan the house marked the churchly pole of a central axis, balanced by the Fürstliches Zehnthaus at the north end. The parish office moved away only in the late 19th century.

The main house is a private residence and not open to visitors; the rear Stallspeicher workshop building stands unused because of ongoing foundation damage. The ensemble sits on the south edge of the Kirchplatz, opposite the St.-Salvatoris-Kirche and next to the old school, so it can be seen while walking across the square.

The theologian Caspar Calvör, born 1650 and died 1725, held his office as Primariuspfarrer and Superintendent in this house from 1684 until he moved to Clausthal in 1710 as Generalsuperintendent. Here he built the Calvörsche Bibliothek, a Baroque scholars' library, and received learned guests in his official rooms.
