The New Cathedral (Mariä-Empfängnis-Dom) construction plans were started in 1855 by Bishop Franz-Josef Rudigier. The first stone was laid in 1862. In 1924 Bishop Johannes Maria Gföllner consecrated the finished building as the Cathedral of the Immaculate Conception. The plans, drawn by the master builder of the Archdiocese of Cologne, Vincenz Statz, were made in the French high Gothic style.
With 20,000 seats, the cathedral is the largest (130 meters long, and the ground 5,170 square meters), but not the highest, church in Austria. The originally-planned, higher spire was not approved, because in Austria-Hungary at the time, no building was allowed to be taller than the South Tower of the St. Stephen's Cathedral in Vienna. At 135 m, the New Cathedral is two meters shorter than the Viennese cathedral.
Particularly noteworthy are the cathedral's stained-glass windows. The most famous is the Linz Window, which depicts the history of Linz. The windows also contain portraits of the various sponsors of the church's construction. During the Second World War some windows, particularly in the southern part of the cathedral, were damaged. Instead of restoring the original windows, they have been replaced with windows displaying modern art. Also noteworthy is the nativity scene in the church burial vault, with its figures made by S. Osterrieder, and the display of the regalia of Bishop Rudigier.
