English: Built in 1831-1834, this Greek Revival and Federal-style church was designed by Laveille and Morton to serve as the Catholic Parish Church for the city of St. Louis, replacing an earlier church built of logs in 1770, which stood on the same site. The building features a rough-hewn limestone and sandstone block exterior, with a tall front portico featuring doric columns, a front pediment, fanlight windows at the outer bays of the front facade, large double-hung windows on the side facades with fanlight transoms, entrance doors at the portico, with a fanlight transom over the central doorway, a steeple with clock faces, pilasters, arched louver openings, and a steeple with a golden cross at the top, a gabled roof, and an elliptical oxeye window and two fanlight bays on the north facade. The interior of the church features doric columns with decorative ornament, a coffered plaster ceiling, altars with corinthian columns, decorative ionic columns at the entrances to the chapels, wooden pews and railings, decorative murals, antique-style chandeliers, and a broken pediment over the altar below an elliptical oxeye window. In 1961, the church was designated a Minor Basilica by the Holy See, and was subsequently rehabilitated in 1963 under the direction of architecture firm Murphy and Mackey. The building is part of the Jefferson National Expansion Memorial, listed on the National Register of Historic Places in 1966. The building was fully restored in 2015-2016, restoring many original features, removing a few later alterations, and modernizing the building’s systems. Today, the church is a popular wedding venue, and is the only remaining historic building east of Memorial Drive in Gateway Arch National Park, though the church remains under the ownership of the Roman Catholic Archdiocese of St. Louis.
