Nuremberg Charterhouse, Carthusian monastery in Nuremberg, Germany.

The Nuremberg Charterhouse, also called Kartause Marienzell, is a former Carthusian monastery founded in 1380 by merchant Marquard Mendel. Its single-nave Gothic church was built in two phases: the eastern parts by about 1383/87 and the western extension by 1405, when dendrochronology dates the roof timbers. A chapter house on the south side gave the plan a cruciform shape; after 1459 it received its own choir and a fan-vaulted ceiling. The small courtyard was finished by 1405. Surviving parts include the large and small courtyards with sections of the vaulted cloister and the monks' houses along the north range.

The Nuremberg Charterhouse was founded in 1380 by the merchant Marquard Mendel. The foundation stone of the Gothic church was laid on 16 February 1381 in the presence of King Wenceslaus and Cardinal Pileus; the first monks are documented from 1382. Dissolved in 1525 during the Reformation, the buildings later served as a gunpowder magazine and from 1857 passed to the Germanisches Nationalmuseum.

The monastery's name Marienzell refers to the Virgin Mary, and the monks' individual houses still line the north range of the cloister. After the Reformation, the church served as a gunpowder magazine from 1552, then as a Protestant church from 1615 and a Catholic one from 1784.

The surviving monastic buildings are now part of the Germanisches Nationalmuseum, so access follows the museum's opening hours rather than a separate monastery entrance. Look for the small and large courtyards with sections of the vaulted cloister, and the monks' houses along the north range of the cloister.

The chapter house that stood on the church's south side was destroyed in World War II and archaeologically investigated only in 1998. Its loss erased the cruciform ground plan formed with the church and sacristy; the small courtyard, by contrast, was finished by 1405 and survives in altered form.
