Roskilde Abbey

It was founded in the early 12th century for Benedictine nuns, but in 1177 became part of the Cistercian reform movement.

It is now the site the Old Church of Our Lady, Roskilde (Gammel Vor Frue Kirke).

[3] After miracles were declared to have happened near her grave, her remains were moved to Roskilde Abbey in 1176 by Absalon of Lund, Bishop of Roskilde, a kinsman of Margrethe; he arranged for the construction of a suitable shrine in the church, and transferred the nunnery to the Cistercians in the following year.

The shrine was nevertheless later declared a place of pilgrimage by the Pope, and the nuns were allotted one third of the income generated by it.

Despite all efforts, however, the center of the cultus remained the small chapel built near Margrethe's original grave on the beach.
