Church of Saint-Sulpice

The church is part of an old Benedictine royal abbey dating from the 6th century. The building was rebuilt by Abbot Morard in the 10th century. The current choir was built in the middle of the 12th century and consecrated by Pope Alexander III. Conventual buildings successively rebuilt during the 13th century. After the Revolution, the church lost its status as an abbey church to become a parish abbey. Reconstructions carried out between 1821 and 1854. Church classified as a historical monument by list in 1862. Remains of the former abbey classified in 1953. Saint-Germain-des-Prés church is the oldest of the great Parisian churches.

The Chapel Sainte Ursule de la Sorbonne or more simply the Sorbonne Chapel is a constituent building of the Sorbonne courtyard. It was the private chapel of the college of the Sorbonne then of the university faculties of Paris in the 19th century. The present chapel was rebuilt in the 17th century by Cardinal de Richelieu and was also his mausoleum. The plan of the former medieval chapel is still visible in the main courtyard of the present Sorbonne, marked with crosses. The foundations of this chapel, consecrated in 1326, were found during the reconstruction of the Sorbonne in 1897.

The church of St. Severin has been a parish church since the 9th century. The Gothic building dates mainly from the 15th century when the church had to be rebuilt after the previous one burnt down. However, the bell tower, the three western bays and parts of the façade have been preserved from the 13th-century building. The ambulatory, which is doubled in size due to the five naves, is considered to be the most architecturally valuable part of the church, while the modern stained glass windows are certainly one of the church's attractions.
