The Church of the Val-de-Grâce is a Roman Catholic church in the 5th arrondissement of Paris. The church was built as part of a royal abbey by Anne of Austria, the Queen of France, to celebrate the birth of her son, Louis XIV in 1638. Construction began in 1645 under the direction of architect François Mansart and was completed in 1665 by Gabriel Le Duc. The abbey and church were turned into a hospital during the French Revolution and then became part of the Val-de-Grâce Hospital, which closed in 1979. The church is attached to the diocese of the French military and is open to visitors at specified hours. Its dome is a landmark in the skyline of Paris.
