Holy Family Church in Cahokia, Illinois, was built of walnut timbers in the poteaux-sur-sol style in 1799, replacing a similar structure built in 1699.
Poteaux-sur-sol ("posts on a sill" – sol is also spelled sole and solle) is a style of timber framing in which relatively closely spaced posts rest on a timber sill. Poteaux-en-terre and pieux-en-terre are similar, but the closely spaced posts extend into the ground rather than resting on a sill on a foundation, and therefore are a type of post in ground construction. Poteaux-sur-sol is similar to the framing style known in the United Kingdom as close studding. Poteaux-sur-sol has also, confusingly, been used for other types of timber framing which have a sill timber such as post-and-plank, but this is considered incorrect by some scholars.[1]
