There were once two parishes in Maintenon: "St. Nicholas," a parish serving the castle and its dependent houses. The church of St. Nicholas, adjoining the castle, now deconsecrated, still stands on Maintenon's main square. "St. Peter," a parish covered by the surveys in this table, is a current parish in the commune. In addition, there was a priory, founded in 1220 under the name of the Priory of Our Lady of Maintenon. The church of Saint-Pierre in Maintenon is mentioned at the beginning of the 12th century, but nothing appears to have survived from this period. Indeed, the Count of Montgomery, a Huguenot, passed through Maintenon in 1567 and ruined the church. In 1692, Madame de Maintenon rebuilt the church of Saint-Pierre, which had fallen into ruin and had become too small for a population that had grown from 700 to 1,100 with the arrival of labor for the construction of the aqueduct. However, there is no evidence that the new church was built on the site of the old one. The foundation stone of the new church of Saint-Pierre was laid on June 4, 1692, by the Vicar General. The blessing took place on July 17, 1694. Bishop Godet des Marais subsequently consecrated the building. In 1736, the large "Henriette" bell was blessed by Mr. Jean François DEREYROLES, parish priest, in the presence of "the Most High and Most Powerful Lord, Monsignor Jean Paul François de NOAILLES, Count of AYEN" and by "the Most High and Most Powerful Lady, Madame Henriette Louise DAGUESSEAU de FRESNE, Countess of AYEN." From 1805 to 1813, Duke Jean-Paul de NOAILLES and his wife refurnished and decorated the Saint-Pierre church (the woodwork, credenzas, and pews were redone). The church's embellishment continued until 1899. The church's architecture is unremarkable. However, it is listed as one of the few Baroque churches in the department. The choir is flanked on one side by a sacristy and on the other by a room called "the vault." This is because, until the 1990s, it contained the bodies of some members of the Noailles family, who were buried there in stacked boxes that are still visible, but disused. The organ, installed in the gallery, is no longer in use. It had been partially dismantled for a renovation that proved too expensive, and some of the pipes were stolen. During the 1939-1945 war, almost all of the old stained-glass windows were destroyed and replaced with modern ones, the work of a master glassmaker from the region: Victor Cot-Dezan.

A short stroll through fields, suitable for a walk of about two hours for all levels, pleasant, but nothing more, quite "flat". The visit to the park and the castle of Maintenon deserve more attention than this walk.

The current remains are those of the 15th-century gate and its barbican or artillery boulevard. The earliest remains on the site date back to the 1st century, with the remains of an ancient domus, a street, and its wooden gutter. The first Guillaume Gate was built around 1185; a wall can still be seen a little further along Rue de la Porte Guillaume. Source: https://journals.openedition.org/cem/14214?lang=en
