A small house of noble canonesses on the Meuse near Roermond, founded about 990, whose abbess is lady of the village of Thorn and a few places around it.
Its imperial immediacy is confirmed only in 1292; in 1200 it is a minor lordship among the counts of Loon, Gelre and the lords of Horn and Born.

Advocates and rivals

Where the sources disagree
Evidence: Only the abbess list and the 1292 confirmation were found; the lordship is drawn as a small disc around the abbey.
On the map: A 3 km disc stands for the abbey's small lordship, because the modern municipality (Maasgouw) is far larger.
