Larreule Abbey was a Benedictine abbey founded by Guillaume Sanche, Duke of Gascony, at the end of the 10th century. The building reached its apogee between the 11th and 14th centuries and was one of the three most important abbeys in Béarn. In decline from the end of the 14th century, it was ravaged in 1569 during the Wars of Religion and finally closed in 1773. Its conventual buildings disappeared during the French Revolution.
