St. Alphonsus Liguori Catholic Church (St. Louis)

St. Alphonsus Liguori Catholic Church, also known as "The Rock Church," is a prominent Roman Catholic church located in St. Louis, Missouri. The church is notable for its distinctive Romanesque Revival architecture, particularly its use of rough-hewn limestone, giving it its nickname.

Founded in 1867 by the Redemptorist order to serve the growing German Catholic population of St. Louis, the cornerstone of the current building was laid in 1869, and the church was dedicated in 1871. The architects were Edwin Jungenfeld and George Helfensteller, Jr.

Beyond its architectural significance, St. Alphonsus Liguori Catholic Church has a rich history of service and outreach to the St. Louis community. The Redemptorist priests who staff the church have been active in social justice initiatives and community development. The church also maintains a strong tradition of liturgical music and art.

The church is located in the Grand Center Arts District of St. Louis and continues to be an active parish within the Archdiocese of St. Louis.
