Labyrinth The cathedral courtyard features the Mary Clark Wright Memorial Labyrinth which was commissioned by her children. The maze is a replica of the Chartres Cathedral pattern and includes lunations, trefoils, and petals sculpted in terra cotta and light gray paving stones. The path is about 12.5 inches wide and the labyrinth is 39 feet in diameter, with a total path length of 750 feet. Work on the project was completed by Labyrinths in Stone, of Yorkville, Illinois, and the dedication ceremony was held in September 2001. The labyrinth was refurbished in 2006 and is available for community use through the church offices.
