La Cité-Limoilou is the central borough of Quebec City, the oldest (in terms of architecture), and the most populous, comprising 21.85% of the city's total population. As an administrative division, it is very new, having only been formed on November 1, 2009, from the former boroughs of La Cité and Limoilou.

Cartier-Brébeuf National Historic Site is a National Historic Site of Canada and so designated by the Historic Sites and Monuments board of Canada in 1958 under the recommendation of John Diefenbaker, the Prime Minister of Canada at the time. It is administered by Parks Canada and located at the confluence of Saint-Charles and Lairet rivers, in Quebec City, Quebec, Canada, more precisely in La Cité-Limoilou borough.

The Lairet River is a tributary of the Saint-Charles River, crossing Quebec City, Quebec, Canada. Over two kilometers long, it took its source in the vicinity of Charlesbourg and flowed in meanders in Limoilou. It has been completely channeled since the 1960s, except for a segment refitted in 2008.
