The former Catholic Diocese of Oloron in south-west France was suppressed after the French Revolution, by the Concordat of 1801. It dated from the 6th century, but its territory became part of the diocese of Bayonne.
The Way of St James passes through Oloron going to Santiago.
The seat of the bishops of Oloron was in Oloron Cathedral in Oloron-Sainte-Marie, now in Pyrénées-Atlantiques. The cathedral has now reverted to a parish church.
Another significant building is Chateau de Lamothe, dating from the early 12th century, when a Moorish fortification on the hill, was destroyed as the French drove the Moorish forces from France, and rebuilt to serve as the summer residence for the bishops of Oloron, a role it filled for 600 years.
