The municipality of Île-Saint-Paul, occupying what was by then universally known as Nuns' Island or Île des Sœurs, was annexed to Verdun in 1956. Then a chiefly agricultural area, it was rapidly urbanized following the opening of the Champlain Bridge in 1962, with development including contributions by the famous Modernist architect Ludwig Mies van der Rohe. Rapid development would continue to the present day, with the erosion of the sensitive natural woodland of the Domaine Saint-Pierre becoming an increasingly pressing concern.
