It is a building dating from the twelfth or early thirteenth century, although it probably existed before an earlier church. The word Prunarias appears in a document from the year 966 as belonging to Sant Pere de Camprodon. The building is mentioned again in 1017. It seems that from shortly after 966 it belonged to the priory of Santa Maria del Coll de Panissars, a situation that must have been maintained until the beginning of the 17th century. In 1617 the church was joined to that of Sant Llorenç d'Oix. In 1661 there were 3 altars: the one of Santa Bàrbara, the one of Santa Caterina and the one of Sant Bartomeu. The church was damaged during the Civil War of 1936-39. The whole complex was completely restored between 1972-1979 by the Friends of Alta Garrotxa.
Inside, different artistic pieces were kept, such as a tombstone representing the burial of a lady from the castle of Bestracà, which was damaged during the riots of 1936. Some of the fragments were deposited in the Museum of Olot by Dr. Joaquim Danès. Until the end of the 19th century, a Romanesque carving was venerated there, today deposited in the Museu d'Art de Catalunya, from the Plandiura collection. The fragments of an altarpiece representing the life of the saint are kept in the Parish Museum of Olot.
From 1972 to 1981, restoration work was carried out, which meant that the building built on the nave during the 17th and 18th centuries was abandoned, as well as the one that turned the old belfry into a tower, rebuilt after a lightning strike. destroyed it in September 1978.
