History and Features
The Mission of the Holy Family was established in 1699 as an outpost of the Seminary of Foreign Missions at Quebec. The current building, the third structure on the site, dates from 1799 and is typical of French colonial post-on-sill log construction, with a cypress clapboard roof, 4’ x 4’ oak beams for the roof timbers, and wooden pegs, rather than nails, used throughout.
The site, prone to flooding, caused the Church’s gradual deterioration through the years, and in 1913 the building was covered with clapboard to prevent further damage. Restoration of the Church took place from 1949 to 1951, following the 250th anniversary celebration of the founding of Cahokia.
Holy Family Church was designated a National Historic Landmark in 1970 and is still used for special services by Holy Family Parish.
The Church is located within easy walk of two other French colonial sites in Cahokia, the Cahokia Courthouse and the Jarrot Mansion (both have entries on this website).
