The building was then severely damaged during the Siege of Quebec in 1759, after which time it passed into British hands.
The house was gradually rebuilt in sections over the next forty years. In the meantime the governors split their time between the St. Louis and a new building, called the New Chateau or Chateau Haldimand after governor Haldimand.[2][3]
The St. Louis was destroyed by fire in January 1834. Afterward it was replaced by a series of terraces.[4]
The site of the New Chateau is now occupied by the Chateau Frontenac hotel, which is named after Governor Frontenac.
Between 2005 and 2007,[6] a series of digs under the Dufferin Terrasse revealed over 500,000 artifacts and ruins of the forts and château.[7] In 2008, for Quebec city 400th anniversary, the remains of Saint-Louis Forts and Châteaux were opened as a Historic Site to the public under the management of Parks Canada.[8]
