| Rijnsburg: Abdij van St. Marie |
Benedictine abbey for women of noble birth. Founded by countess Petronella (countess of Holland) in 1133, dedicated to St Laurentius and the virgin Mary. The first inhabitants were nuns of Stötterlingenburg (Saxen).
Together with the Adelbertusabdij the abbey was placed directly under the authority of the pope in 1140. The Rijnsburg abbey gained power, whereas the Egmond abbey lost power; already in the 12th century the counts of Holland had themselves buried in Rijnsburg.
From 1176 onwards the abbey possessed a parish church: the Laurentiuskerk.
Round 1500 the abbey joined the Bursfelder Congregatie. Round 1537 some attempts have been made to reform the abbey into a chapter (collegium of canonesses). The abbey was destroyed in 1574.
The manuscripts of this abbey contain many chants for St Adelbertus of Egmond.
