Archeological excavations on the site of the old convent in 1998 uncovered the vestiges of a seigneurial windmill. This structure, built circa 1655, was used as a prison in the 1730s. The excavations also helped document the everyday lives of nuns and students at the convent, especially their diet and their remedies.Picture: Painting of the windmill’s vestiges (James Pattison Cockburn, 1830.
