The center of Catholic worship in the diocese of Lafayette, was first built in 1821. The present structure was completed in 1916, and is listed in the National Register of Historic Places.

Adjacent to the cathederal is the St John oak. A massive live oak tree, over 400 years old.
A photo-depiction of the scene can be seen at the church's website.
