One of the most important names in medieval architecture in the Netherlands is that of the Keldermans family, of which seven generations were architects and sculptors, especially working in the Brabantine Gothic style. Originally named Van Mansdale, the family originated from Brussel and later settled in Mechelen. Both these cities were among the most important of the Duchy of Brabant and are now in Belgium. Although much of the family's work was in the Duchy of Brabant, they had several assignments in Holland and Zeeland as well. This page deals with their work in the current Netherlands only, and is incomplete.
