The Basilique Saint-Urbain de Troyes is a massive medieval church in Troyes. It was a collegial church, endowed in 1262 by Pope Urban IV. The builders encountered resistance from the nuns of the nearby abbey, who caused considerable damage during construction. Much of the building took place in the 13th century, and some of the stained glass dates to that period, but completion of the church was delayed for many years due to war or lack of funding. Statuary includes excellent examples of the 16th century Troyes school. The vaulted roof and the west facade were only completed in the late 19th and early 20th centuries.
Saint-Urbain is a classic example of French Gothic architecture of this period. The exterior has perforated gables with sharp points, narrow buttresses with many pinnacles, and openwork flying buttresses. The sober, elegant interior of the church is filled with light from the huge windows.

Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
