The Minority Church was founded in 1275, becoming one of the first Gothic churches in Vienna. The first changes in the architecture of the building occurred quite quickly: in 1328 a chapel was built in honor of St. Louis IX. The chapel had a separate entrance and did not connect to the church. However, the union took place already in 1340, creating a three-nave single room.
For many years, the church existed unchanged. Twice during the Turkish sieges in 1529 and 1683, the tower was partially destroyed. Strong changes occurred during the eviction of minorities due to the policy of Emperor Joseph II in 1782. The church was proclaimed Italian and consecrated in honor of Maria Snezhnaya, under whose auspices the church exists today. Minorites took with them to Wimpassing a cross with the icon of Christ, which was located above the altar. An exact copy of such a cross is in St. Stephen's Cathedral.
At the beginning of the 19th century, a mosaic copy of The Last Supper by Leonardo da Vinci was installed in the church. Mosaic was completed in 1809 by Giacomo Raphael commissioned by Napoleon. It was intended for the Belvedere, however, was too large for those interiors (9.18 m by 4.47 m). The weight of the copy is 20 tons and is the largest reproduction of the fresco. The artist completed his work on stone mosaic tablets. The canvas is created from 12 plates that hold ten thousand stones of various sizes. Some mosaic elements are measured in just a few millimeters.
When the mosaic was completed, Napoleon was overthrown, so Franz I had to pay for the order.
In 1900, the last changes took place, in particular, the construction of gift-keepers. During the construction of the metro in the late 1980s, the foundation of the chapel of Louis was found, which is located in the square near the church.
