Friar Bo is named in a 1267 letter connected with the conflict between Archbishop Jacob Erlandsen and King Valdemar.
Prior Petrus Brackæ gave all his worldly possessions to Sorø Abbey in 1312 and then became a Dominican at Roskilde.
[4] The greatest patron of the Dominican friars of Roskilde was the immensely powerful Dowager Duchess Ingeborg (1301-c.1360), mother of King Magnus IV of Sweden and VII of Norway, who made them frequent gifts from at least 1330 onwards and also remembered them in her will.
The Roskilde friars forged over time a close connection with the cathedral chapter in the city, which to an extent insulated them from the ebb and flow of events in Denmark's turbulent Middle Ages.
[3] Few details are known of the priory buildings, which were sited a little to the north of the modern Roskilde Kloster, but they consisted of a brick church consecrated to Saint Catherine in 1254, dormitory, scriptorium, refectory and a garden, which included an apple orchard.
Christian III, who with many Danes opposed the constant appeal for funds by the mendicant orders, commanded the closure of the priory in 1537 and the Dominican friars were turned out.
