The small town of Langres was once the capital of the Romanized Gallic tribe known as the Lingones. At a later date the Romans fortified the town, which they called Andemantunum, located at a strategic crossroads of twelve Roman roads. The first-century Triumphal Gate and the many artefacts exhibited in the museums are remnants of the town's Gallo-Roman history. After the period of invasions, the town prospered in the Middle Ages, due in part to the growing political influence of its bishops.
The troubled 14th and 15th centuries caused the town to strengthen its defenses, which still give the old city its fortified character, and Langres entered a period of royal tutelage. The Renaissance, which returned prosperity to the town, saw the construction of numerous fine civil, religious and military buildings that still stand today. In the 19th century, a 'Vauban' citadel was added.
Today Langres has a historic town center surrounded by 13km long defensive walls, with a dozen towers and seven gates.
Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
