Notre-Dame du Haut is a Roman Catholic chapel in Ronchamp, France. Built in 1955, it is one of the finest examples of the architecture of Franco-Swiss architect Le Corbusier. The chapel is a working religious building and is under the guardianship of the private foundation Association de l’Œuvre de Notre-Dame du Haut. It attracts 80,000 visitors each year. In 2016, it was inscribed on the UNESCO World Heritage List in along with sixteen other works by Le Corbusier, because of its importance to the development of modernist architecture.

A chapel is a Christian place of prayer and worship that is usually relatively small. The term has several meanings. First, smaller spaces inside a church that have their own altar are often called chapels; the Lady chapel is a common type of these. Second, a chapel is a place of worship, sometimes interfaith, that is part of a building, complex, or vessel with some other main purpose, such as a school, college, hospital, palace or large aristocratic house, castle, barracks, prison, funeral home, cemetery, airport, or a military or commercial ship. Third, chapels are small places of worship, built as satellite sites by a church or monastery, for example in remote areas; these are often called a chapel of ease. A feature of all these types is that often no clergy were permanently resident or specifically attached to the chapel.
