The Old Cathedral is a St. Louis landmark that has stood its ground. It escaped the St. Louis fire of 1849 and a massive demolition program in the 1930s to make way for the Jefferson National Expansion Memorial project. Turns out that over time, it was moisture that became the landmark’s biggest foe.

When the Archdiocese of St. Louis decided to embark on a major restoration program, they chose Mackey Mitchell as the architect. Working closely with historic masonry specialist John Speweik of Chicago, Il; Musick Construction Company; mason contractor Superior Waterproofing and Restoration; and stone supplier Earthworks among others, the entire team has brought the interior and exterior architectural design features back to life. “It has really come together,” said Father Richard Quirk, in a recent St. Louis Review article. ” We’ve enjoyed a lot of compliments.” Mackey Mitchell congratulates the entire group’s effort along with Mackey Mitchell’s team of Gene Mackey, Lea McRoberts, John Brown, and Avik Guha for helping preserve and restore this significant St. Louis landmark.
