Notre Dame de Paris

The church of Saint-Julien-le-Pauvre is a medieval church built in the 12th century on the site of a primitive basilica destroyed by the Vikings. The priory to which the church was attached has long been prosperous, and the church has even hosted courses from the University of Paris. In the 17th century, the priory fell into decay and the church fell into disrepair. In the middle of the 17th century, the church and priory were given to the Hôtel-Dieu de Paris, which turned the church into a chapel. The French Revolution led to its transformation into a warehouse, a situation that lasted until 1826. Then Saint-Julien-le-Pauvre became a hospital chapel again until 1873. Since 1888, the Greek-Catholic Melkite community made the church its parish church. It remains the centre of the life of the Greek-Catholic Melkite parish in Paris.

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.

Saint-Gervais is considered one of the first parishes on the right bank. The remains of an ancient cemetery and a vast Merovingian necropolis discovered around Saint-Gervais would explain the age of the foundation. The church was consecrated in 1420, then enlarged from 1494 until about 1620. The facade is the first of a church to use the classical vocabulary of orders in a monumental way, in accordance with the ancient fashion that prevailed in the 16th and 17th centuries. It was closed in 1793 and reopened in 1795 and shared between Catholics and theophilanthropists until the Concordat. On Good Friday, March 29, 1918, a German shell destroyed part of the nave in the middle of the mass, killing about a hundred people.
