Foch Square, Saint-Omer

Highlight • Historical Site

The town hall was built between 1834 and 1841 with materials from the church of the Abbaye de Saint-Bertin. At the heart of the building is an Italian-style theatre. The Hôtel de Bailliage is a former royal court that was outside the power of the aldermen. It is an elegant Louis XIV building, decorated with pilasters, Doric capitals, ironwork and floral garlands. Four statues on the balustrade symbolise the cardinal virtues.

The old parish church of St. Michel du Wast was built at the end of the 11th century by Ide, Countess of Boulogne. Ide was the mother of Godefroi de Bouillon and was buried in this church on April 20, 1113. One can see the carved stone that covered her tomb.
The portal, in all its Byzantine beauty, has remained standing . It is a beautiful Romano-Byzantine portal, the plan of which has been published in the collection of departmental antiquities .
Oriental foliage decorates the portal of the Romanesque church. The round arches rest on capitals of water leaves rolled into volutes.

The village already existed in the seventh century, in the year 823 it belonged to the Abbey of Saint-Riquier. In 881 it was completely destroyed by the Normans, only in 1065 it was mentioned again as the Count of Flanders Baudouin-le-Barbu at the request of Bishop Druon, the church of Pernes, the outbuildings, and a piece of land and a plow at the chapter of Therouanne.
In the following period, Pernes was one of the seven châtellenies of the County of Saint-Pol. In the 12th and 13th centuries, the barony of Pernes belonged to the house of Bailleul, in the 14th century to the counts of Fauquembergue. In 1371 it came back into the possession of the Count of Saint-Pol through a marriage, and it is also known that Maximilien van Vignacourt was the owner in 1695.

The church, Eglise du Saint-Esprit, was built in the years 1851 - 1852 by contractor M. Sagnier, the design was by architect Philippe Sannier. The year 1850 is written on the bell tower.
