Holy Family Church in Cahokia, Illinois. The parish was founded in 1699 and is the oldest continuously operating parish in the United States. The log church was built in 1799. The church was built in the poteaux-sur-sole (post on sill) style. The spaces between the upright logs were filled with stone and mortar chinking.

The building in the background was constructed using the piece-sur-piece method of construction. The Church and warehouse in Detroit were constructed using the piece-sur-piece method of construction. The building in the foreground is the blacksmith's shop; it was built in the poteaux-en-terre (posts in the earth) sytle. The houses in Detroit were also built in the poteaux-en-terre (posts in the earth) style, although they were roofed in thatch. See pages 3 and 4 of the 1710 Census on our Land and Census Information Page which describe the houses, Church, and warehouse.
