Roermond Charterhouse

It was founded in 1376 by Werner van Swalmen, a canon at Maastricht, after he had returned from a pilgrimage to the Holy Land, and settled by 12 monks from Cologne Charterhouse.

The important and prolific 15th-century theologian Denis the Carthusian (1402–1471) was a monk here.

The monastery was destroyed by fire in 1554 and pillaged by the army of William the Silent, Prince of Orange, in 1572, when half the monks were killed, subsequently known as the Martyrs of Roermond.

The monastery enjoyed prosperity in the 18th century but was suppressed under the Josephine Reforms in 1783.

The mediaeval monastic chapel, re-dedicated to Saint Charles Borromeo in 1841, continues in use as a church.
