St Omer Attractions 
St Omer (pop. 16,595), formerly belonging to the County of Flanders, lies in Artois, between Calais and Lille. The town grew up around a Benedictine monastery founded in the seventh century. In the west of the town, on Place du Maréchal-Foch, is the modern Hôtel de Ville (Town Hall), which also houses the Municipal Theater.
East of the Town
On the east of the town are the ruins of the abbey of St-Bertin, founded in 1640. Northeast of the Town Hall is the church of St-Sépulcre (13th-14th century).
Helfaut - La Coupole
La Coupole was built in 1943-44 by the Nazis as the base and launch against London during World War II. The enormous dome of concrete was constructed above the site to protect it. In 1987, it was transformed into a place of education and remembrance. In early 1997, the Historic Centre of War and Rockets was linked to La Coupole.
