Saint-Julien-le-Pauvre is a Melkite Greek Catholic parish church in Paris, France, and one of the city's oldest religious buildings. It replaced a Merovingian refuge for pilgrims, or an older church dating back to the 6th century. The earliest mention of such a site was found in texts authored by Gregory, bishop of Tours, who resided there during the rule of Chilperic I, king of Neustria. A synagogue serving the Jewish residents, probably the oldest in the city, was located in its environs.
The new building, inspired by either the Notre Dame Cathedral or the Saint Pierre de Montmartre church, was begun ca. 1165-1170. The building effort was supported by the Clunaic monastic community of Longpont, and their enterprise resulted in the completion of the choir and, most likely, the nave (ca. 1210-1220). According to 16th century chronicler Étienne Pasquier, the site was connected with the University of Paris foundation, serving as a site for its School of Theology and Arts, and, after the resulting split between the faculties, only as the School of Arts.
All early construction seems to have stopped ca. 1250. In 1651, following several centuries of neglect, two of the original bays in the nave were demolished, and a northwestern facade was added; the northern aisle was preserved, and two of its bays serves as a sacristy. After more than a century, during the French Revolution, the building was listed for demolition, and suffered more damage as a result. Before the second half of the 19th century, Saint-Julien-le-Pauvre underwent restoration under the direction of architect Franz Christian Gau.
In 1889, under the Third French Republic, the church was awarded to the Melkite (Arab and Middle Eastern) community in Paris. In preparation for this, significant restoration was again carried out.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
