Theological Hall itself was built in 1879, and designed by Gordon & Helliwell. Funded completely by donations from the citizens of Kingston, the cornerstone of Theological Hall was laid in 1879 by the Marquis of Lorne, Governor-General of Canada, and his wife, Princess Louise, the fourth daughter of Queen Victoria, and the building was completed in October 1880. The third-oldest building on the Queen's University campus, the massive limestone structure was built in Norman Romanesque style, featuring its trademark double-oak front doorway and central tower flying the Canadian flag. Originally built to house the Faculty of Arts and Science (and to this day is often referred to as the Old Arts and Science Building), Theological Hall was the university's main building throughout the late 19th century. The building features an ornate mediaeval-style Convocation Hall that served the university for convocation ceremonies until Grant Hall was built (between 1902–05), and at one time a circular library at the west end of the building. Morgan Memorial Chapel, with its old-world vaulted ceilings and ecclesiastical stained-glass windows depicting scenes from the Hebrew Scriptures and the New Testament, was named in honour of the late professor of Theology, William Morgan, and serves the entire university community.
