One of the most important Neo-Gothic religious architectural sites in the world, constructed between 1856 and 1879. Stands on a large square on the location where an unsuccessful attempt to assassinate Emperor Franz Joseph took place in 1853. The plans were established by Heinrich von Ferstel (1828-1883), who chose to build the cathedral, borrowing heavily from the architecture of Gothic French cathedrals. It is made of white sandstone, similar to the Stephansdom, which is very vulnerable to air pollution and acid rain and therefore requires frequent renovations.

The Votivkirche (English: Votive Church) is a neo-Gothic style church located on the Ringstraße in Vienna, Austria. Following the attempted assassination of Emperor Franz Joseph in 1853, the Emperor's brother Archduke Ferdinand Maximilian inaugurated a campaign to create a church to thank God for saving the Emperor's life. Funds for construction were solicited from throughout the Empire. The church was dedicated in 1879 on the silver anniversary of Emperor Franz Joseph and his wife Empress Elisabeth.
