Saint-Germain d'Auxerre Church

Highlight • Religious Site

On the site of a former priory, the church of St Germain d'Auxerre of Romanesque origin is erected on a mound planted with chestnut trees on the site of the old cemetery.

In the choir, we can see a beam of glory with Saint John and Saint Mary Magdalene.

The south chapel contains an altar, a tabernacle and an 18th century altarpiece as well as a painting of Saint Barbara.

You can also admire a 16th century Virgin and Child and bird (gift from the Jouvin family) and the 18th century baptismal font is framed by two paintings. A Damien organ from 1859, with original 13-note pedal board, still plays. A large textile fresco was embroidered by the Benedictine sisters.

Porte Saint Denis

Highlight • Other

Last vestige of Fort Toussaint, it marks the entrance to the formerly fortified old town, with its many historic buildings and monuments.
Favorite holiday resort of the Counts of Perche and their wives, Mortagne-au-Perche is indeed endowed with a remarkable historical heritage with 17 sites listed in the inventory of historical monuments. The heart of the city shelters the clearly visible architectural traces of a former walled city: including the Porte Saint-Denis, the Crypt Saint-André (remains of the former Collegiate Church of Toussaint), but also the Cloister and the Chapelle Saint- Francois. It is still possible to walk along its ramparts, to discover its cobbled streets and alleys, its walled gardens, ... specific to medieval cities.

Saints Louis and Zélie Martin lived here, with their 9 children, who all entered religious life. Saint Thérèse of Lisieux is the best known. This museum is warm and extraordinary, with a small garden and a chapel. A jewel of Alençon ✨✨✨

Crossing the Sarthe, you come across this "Monument Leclerc", a memorial paying homage to General Leclerc, commander of the 2nd Armored Division, who liberated the town of Alençon on August 12, 1944. On the wall are the main dates and places that marked the course of the 2nd DB. Opposite, there is one of the many terminals of the Koufra oath.

Alençon Courthouse

Highlight • Monument

Very nice building! It could be a princely palace! Oh no, the reality is much more sordid: it's the place where lawyers twirl around, judges bang hammers, and poor people are heavily sentenced while rich people put their powerful nets to use.

The castle of the Dukes of Alençon is an old fortified castle, from the end of the 12th century. Its remains stand in the heart of the French commune of Alençon in the Orne department, in the Normandy region. During the Revolution, the remaining buildings of the castle were transformed into a prison, a function which it retained until 2010. The castle is classified as a historic monument.

Saint Leonard's Church

Highlight • Other

The Saint-Léonard church takes its name from the hermit Saint Léonard de Vandoeuvre. The latter, born at the end of the 5th century, left his family to serve God and settled in a place called Vandoeuvre, in Saint-Léonard-des-Bois, where he lived in austerity for several years. Joined by a few disciples, he built a monastery protected by King Clotaire. The relics of Saint Leonard, who died in 570, were transported in 868 to Corbigny by the monks of Vandoeuvre to preserve them from the Normans. Part of these was undoubtedly returned around 1025 thanks to the second lord of Alençon, William I, and deposited in an old chapel dedicated to Saint Martin located on the site of the current Saint-Léonard church. This saint is often invoked to cure deafness.

A first Saint-Léonard church, attested between 1160 and 1182, was probably built very close to the Saint-Martin oratory. This disappeared around the middle of the 13th century in forgotten circumstances, but parish life remained concentrated in the chapel until the end of the 15th century.

It is on the latter that the current church was built, in tertiary ogival style and flamboyant Gothic interior, by Duke René d'Alençon and his wife Marguerite de Lorraine. Most of the work took place from 1490 to 1505 and it was this same year that the building was placed under the name of Saint Leonard de Noblac, a character then more popular than Saint Leonard de Vandoeuvre.

On the stained glass windows of one of the eleven side chapels, which was for a certain time dedicated to Louis IX, ancestor of the counts and dukes of Alençon, and on the walls, appeared the coats of arms of the houses of Alençon and Lorraine, today now disappeared. It was in this chapel that the duchess and the duke attended services and in which a fireplace was built for them which no longer exists. After René's death, his heart is placed in a lead box, itself in the shape of a heart, covered with a stone. When around 1510, René's heart was transferred to the church of Saint-François de Mortagne, the empty box was left in his vault. In 1776, the stone, which also bears the imprint of a heart, was removed, then put back in its place, and this imprint, erased by the friction of the feet, no longer exists except in memory. In 1562, the church was pillaged by Protestants. At Easter 1645, Hertré's granite vault collapsed. Replaced by a simple plaster cradle, it was not until 1836 that a new Gothic style vault was built. The main door was built in 1663 and the clock was installed in 1727. Until 1789, this church depended on Notre-Dame and did not have a baptismal font. The carved wooden altar and pulpit, two side consoles and some mostly modern stained glass windows, deserve the tourist's attention. The Saint-Léonard church, restored in the 17th-18th centuries, then completely refurbished in the 19th century by the architect Isidore Dédaux, is classified among the historic monuments.
