granite from St. Cloud, Minnesota (from the Clark quarry). The interior walls are American Travertine from Mankato, Minnesota. The interior columns are made of several types of marble. The interior is illuminated by twenty-four stained glass windows featuring angelic choirs. There is also a rose window in the transept designed by Charles Connick. Electric lighting was installed in 1940. Heroic size marble statues of the four evangelists, sculpted by John Angel, are set into the niches of the piers in the four corners of the church. This placement was not coincidental, according to Msgr. Lawrence Ryan (Historical Sketch of the Cathedral of St. Paul, 1904–1937), for as the piers hold up the church of stone, so the Word recorded by Matthew, Mark, Luke and John sustains that Church not made by human hands. Each statue rises to a height of 11’6” and weighs eight tons. The life of Saint Paul is honored by a bronze baldachin, as well as massive bronze Te Deum and Magnificat grilles. The cathedral also has six chapels dedicated to the patron saints of the European ethnic groups that settled the area around the city: St. Anthony for the Italians, St. John the Baptist for the French Canadians, St. Patrick for the Irish, St. Boniface for the Germans, Saints Cyril and Methodius for the Slavs; and St. Therese of Lisieux for the missionaries. There are also chapels dedicated to the Sacred Heart, to Mary, the mother of Jesus, and to Saint Joseph, her husband, as well as to Saint Peter.
