Château de Colembert

Highlight • Castle

The Castle of Colembert is located in the village of Colembert, in the Pas-de-Calais department, France. The land of Colembert was made a marquisate by Louis XIV in favor of Gabriel de Maulde. Anne-Louise d'Isques married it to Count de Sainte-Aldegonde in the mid-18th century. The current castle was built between 1776 and 1784 by architect Giraud Sannier for Count Charles de Sainte-Aldegonde on the site of an old castle. It was confiscated during the Revolution and sold as a national asset. Louis-Charles de Sainte-Aldegonde, son of the former owners, was able to buy back the castle. The current owner is Baron Olivier Law de Lauriston-Boubers, descendant of Louis-Charles de Sainte-Aldegonde .
