Red Vault
The priory was founded in 1367-1369 from a small vault[2] that existed since 1366. In 1368, Willem Daniëls, together with two colleagues, priests from the Brussels Saint Gudula chapter, started a vault just outside the city of Brussels. The name Roode Cluyse that was given to the wooden house was, according to some, derived from the color of the layer of crushed brick with which it was covered. A more scientific explanation for the name is its location in an open, cleared place in the forest (a 'ro' or 'rode'), such as at nearby Sint-Agatha-Rode, or Gruitrode, Herkenrode, Sint-Oedenrode, Rolduc and so on. A third (less likely) possibility is the meaning cross, compare the Old English red (from the Proto-Germanic rodo).[3] In Old English this was the only word for the Cross of Christ.
Priory
After living as hermits for six years, the Rule of Augustine was adopted in 1374 and the hermitage became a priory: Willem Daniëls became prior, fellow priests Godefried van den Lare and Henricus de Angulo became Augustine, Walter van der Molen became a lay brother. In the 15th century, the priory expanded considerably. The painter Hugo van der Goes lived and worked there during the last years of his life. He died there, insane, in 1482. Between 1635 and 1638 a new marble altar was made for the Onze-Lieve-Vrouw-ten-Poelkerk in Tienen.
