Saint-Hilaire, Paris

The Church of Saint-Hilaire or Saint-Hilaire-du-Mont  is a ruined 12th-century church in Paris, France, active until the French Revolution.

History
An original oratory was built on the site in the 11th century. The site is located on Montagne Sainte-Geneviève on a plot that belonged to the canons of Saint-Marcel.

In 1158, the building was attested as a parish chapel dedicated to Saint Hilary. The small parish had numerous bookshops —up to 14 on Rue Saint-Hilaire in 1571.

During the French Revolution, the church was closed in 1790 and the parish was suppressed in 1793. It was sold as a national good in 1796 and demolished in 1807.

Architecture
A drawing of the church shows that the bell tower was made of carpentry with no masonry.

Ruins
The ruins of the church are located at 2 Rue Valette and 1bis Rue de Lanneau in the 5th arrondissement of Paris.

The few remains include a column with a capital and a part of an arch. They can be seen in a small courtyard that can be reached from 1bis Rue de Lanneau near the corner of the Rue Vallette.
