Place D'Youville, Historical square in Old Montreal, Canada

Place D'Youville is a square in Old Montreal that tells the story of different historical periods through its materials: wooden walkways connect to concrete, granite, and limestone surfaces. The space opens toward museums, offices, and restaurants, while wide seating areas invite visitors to linger.

The first Montreal settlers landed near this spot on the Saint-Pierre river in 1642, but the flood-prone land was soon abandoned for higher ground. The Hôpital général, built 1692–1694 for the poor, stood on the surrounding land; the Grey Nuns of Marguerite d'Youville ran it from 1747. In 1833 the Georgian St. Anne's Market was built here, housing the Parliament of the Province of Canada from 1844 until English-speaking demonstrators burned it on 25 April 1849 over the Rebellion Losses Bill; Montreal lost its capital status. Rebuilt in 1852, the market was demolished in 1901, and the square was named for d'Youville, one of its first residents.

The square takes its name from Marie-Marguerite d'Youville, who from 1747 ran the General Hospital for the poor on land around the present square with her Congregation of the Grey Nuns. The city chose the name in 1901, calling her one of the first residents of the spot. The former fire barracks in the centre housed the Centre d'histoire de Montréal until 2018.

The square links Place Royale to rue McGill, with the Pointe-à-Callière museum on its south side and the former fire station that housed the Centre d'histoire de Montréal in the centre. The site was dug over for archaeological excavations from 2010 to 2018, so parts of the surface may be fenced or resurfaced. It became a square in 1902 and served as a parking lot in the 1930s.

Archaeological digs on the square from 2010 to 2018 uncovered thousands of artefacts; the site was declared a heritage site by Quebec in 2012, and the Pointe-à-Callière museum was to occupy it around 2022. The square was laid out as a garden in 1902 and became a parking lot in the 1930s.
