The register’s text, word for word
Description
Located at the corner of Notre Dame and Berri streets, in downtown Montreal, this masonry building occupies a little more than half of its urban lot. The two semi-detached houses occupying this lot had been part of a three house urban terrace on what had been the site of the Montreal citadel . One part of the house presents the life and work of Father of Confederation George-Étienne Cartier, upper-middle class Montrealer, politician and Father of Confederation, and the other has been restored to present the domestic setting of the Cartier family during the 1860s.
Heritage value
Sir George-Étienne Cartier National Historic Site of Canada was commemorated because:
- these two houses together served as the residence of a major Canadian political figure,
Sir George-Étienne Cartier,
- Cartier was the Prime Minister of the Province of Canada between 1858 and 1862;
- Cartier was one of the principal Fathers of Confederation
- Cartier was one of the most influential members of the first Canadian cabinet.
The heritage value of Sir George-Étienne Cartier National Historic Site of Canada resides in its association with George-Étienne Cartier, whose political career lasted from 1848 to 1873, and in its illustration of an upper-middle class Montreal home in the middle of the 19th century, showing both French and English architectural influences.
