The cathedral is an unfinished building, with only two-thirds of the proposed building completed, due to several major stylistic changes, work interruptions, and unstable ground on the site. In 1892 construction began on the original design, a synthesis of the Byzantine Revival and Romanesque Revival styles. After the opening of the crossing in 1909, the overall plan was changed to a Gothic Revival design. The completion of the nave was delayed until 1941 due to various funding shortfalls, and little progress has occurred since then, except for an addition to the tower at the nave's southwest corner. After a large fire damaged part of the cathedral in 2001, it was renovated and rededicated in 2008. The towers above the western elevation of the facade, the southern transept, and a proposed steeple above the crossing, have not been completed.
