Merck-Saint-Liévin (pronounced as /fr/; pcd|Merck-Saint-Lévin; vls|Sint-Lievens-Merk) is a commune in the Pas-de-Calais department in the Hauts-de-France region of France.[2]
Merck-Saint-Liévin lies about 10 miles (16 km) southwest of Saint-Omer, on the D225 roads. The river Aa flows through the village.
The name apparently refers to Saint Livinus of Ghent (martyred in 657 or 663), an Irish bishop who evangelized Flanders and Brabant, and is highly venerated in northern France.
The Chemin de fer d'Anvin à Calais opened a railway station at Merck-Saint-Lièvin in 1881. The railway was closed in 1955.
