Marmoutier is a commune in the Bas-Rhin department of Grand-Est, northeastern France, on the banks of the Rhine River.

Its name derives from the Latin 'Maius Monasterium', referring to a large Benedictine abbey founded there in the 7th century.

The abbey played a significant role in the conversion of the region to Christianity and became a major intellectual and religious center.

In the 10th century, Marmoutier became part of the Holy Roman Empire, and its strategic location on the Rhine made it a contested territory throughout the Middle Ages.

The commune's population has steadily grown over the centuries, reaching approximately 2,600 inhabitants today.

Marmoutier's economy is primarily based on agriculture, with viticulture being a major industry.

The town is also home to several small businesses and industries, including a historic paper mill and a glass factory.

Marmoutier features a notable architectural heritage, including the ruins of the Benedictine abbey, a Romanesque church, and several medieval houses.

The commune's cultural traditions include the annual Saint Bartholomew Festival, which celebrates the patron saint of the town.

Marmoutier has played a minor but notable role in French national history, with its Benedictine abbey serving as a refuge for persecuted Huguenots during the 16th and 17th centuries.

Despite its modest size, Marmoutier has made significant scientific contributions, particularly in the field of astronomy.

The town's observatory, founded in the 19th century, has been instrumental in the discovery of several asteroids and comets.

Marmoutier is not home to any UNESCO World Heritage sites but is part of the UNESCO Biosphere Reserve of the Vosges du Nord.

The commune has a vibrant community life, with numerous cultural and sports associations contributing to its social fabric.

Marmoutier remains a charming and historic town, offering visitors a glimpse into its rich past while showcasing the vitality of contemporary life in the Alsace region.
