The L'Arche Community in Clinton Iowa is known as "The Arch." As explained by L'Arche USA, "L'Arche Communities, founded by Jean Vanier in France in 1964, bring together people, some with developmental disabilities and some without, who choose to share their lives by living together in faith-based communities. The first L'Arche community in the United States was founded in 1972, and there are now 16 communities nationwide." The Arche was founded two years later, in 1974, by a Clinton Franciscan, Sr. Marjorie Wisor, OSF.
