On this site on the heights of Québec City close to the Château Saint-Louis (recognized by the HSMBC in 2002), Bishop Saint-Vallier (recognized in 1990) built the Episcopal Palace in 1693–95. From 1777 the building served a new function: rented by the government, it housed the Legislative Council of Governor Guy Carleton (recognized in 1974) and, from 1791 to 1838, the Lower Canada House of Assembly. This is where the first patent for a Canadian invention was issued, in 1824 (recognized in 1923).
