Saint-Omer station

Highlight • Monument

Located in Saint-Omer, France, the Gare de Saint-Omer has a rich history dating back to the 19th century. The first version of the station opened on September 1, 1848, as part of the railway line from Lille to Calais. The original building was modest and located outside the city walls, between the Porte de Lyzel and the Porte du Haut-Pont.
In 1904, a new, monumental station building was inaugurated, designed by the architect Clément Ligny. This building, with its neoclassical architecture, was built with high-quality materials such as blue stone from Soignies and white stone from Creil. The design reflects the grandeur of a 17th-century castle, complete with symmetrical pavilions and decorative elements such as triglyphs and pediments.

Saint-Omer Cathedral

Highlight • Other

You will see the tomb of St. Audomarus and the mausoleum of Eustache de Croy, chapter provost in Saint-Omer and bishop of Arras, a moving work by Jacques Dubroeucq (16th century). He shows the deceased kneeling, in bishop's robes, but also lying down and naked, as in classical antiquity. Note the 15th-century tombstones with inscriptions and the Descent from the Cross by Rubens (first bay of the right aisle). The tombs are 15th century, the alabaster statues 16th and 17th centuries. Other eye-catchers are the Madonna with cat (right aisle), the statue (13th century) of Notre-Dame des Miracles that attracts pilgrims every September, a Nativity of Christ from the 13th century and the tomb (8th century) of St. Erkembode, abbot of Saint-Bertin - here they leave shoes of children who have difficulty learning to walk. Above the astronomical clock (1558) a jaquemart tolls the hours (transept left). Above it is a rose window in flamboyant style. The statue group Grand Dieu de Thérouanne (13th century) stood 20 m above the portal of the cathedral of Thérouanne, which was destroyed by Charles V. The figures seem distorted, but the artist foreshortened them so that they had the correct perspective from below (transept left).

After being closed for several years, the Saint-Omer train station has been given a facelift. The new, completely renovated building is dedicated to travelers, of course, but also to artists, craftspeople, entrepreneurs… La Station isn't just a station; it's "a space for innovation with a station inside."
