The Chapel of St. Thomas Aquinas is located on the St. Paul North Campus of the University of St. Thomas. Archbishop John Ireland announced on April 11, 1916 that a chapel would be built at the College of St. Thomas. Emmanuel-Louis Masqueray, the architect of the St. Paul Cathedral, the Co-Cathedral of the Basilica of St. Mary, and the Church of Saint Louis, was chosen to design the adaptation of the Byzantine style used for basilicas in several northern Italian cities during the Renaissance, with a pattern based on the Latin Cross. The first celebration in the chapel took place on the feast of St. Thomas Aquinas, March 7, 1918.
