The Cathedral District, named after the Art Deco Cathedral of the Holy Spirit, is an historic neighborhood near downtown Bismarck. Some homes in this neighborhood date to the 1880s, although many were built in the first decades of the 20th century. At times, the city has proposed widening the streets in the neighborhood to improve traffic flow. Many residents object because such a project would require the removal of many of the towering American elms which line the streets. These have escaped the elm disease that destroyed street canopies of trees in eastern cities.
