Panthéon

Saint-Étienne-du-Mont Church was built at the end of the 15th century on the site of a 13th-century church, but its rich Renaissance façade was not completed until 1624. Until the French Revolution, the church housed the relics of Sainte Geneviève, patron saint of Paris. The church also houses an organ from the 1630s.

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.
