Once she was declared Governor of the Netherlands, Margaret purchased the palace of Jean Laurin, Lord of Watervliet, located in the Korte Maagdenstraat (Virgins Short Street). She found the residence too small and started an ambitious expansion campaign in 1507. From 1517 to 1530, the architect Rombout II Keldermans furthered the project along the Keizerstraat (Emperor Street) and modified what became the rear wing, which faces the Palace of Margaret of York. The Governess kept several painters at her court, including the Master of the Legend of the Magdalen and Pieter van Coninxloo.
