The travertine stone used for the construction originates from the Souppes-sur-Loing quarry.
The building was partially funded by a public subscription, with donors' names often carved into the stone of the interior walls.
The 'Savoyarde' bell weighs 18,835 kilograms and its clapper alone weighs 850 kilograms.
The mosaic of Christ in Majesty, created by Luc-Olivier Merson, is composed of over 25,000 enamel and glass tiles.
The basilica was built as a 'vow of penance' following the social and political upheaval of the Paris Commune.
The central dome is accessible to visitors, offering one of the highest panoramic vantage points in the city.
The site sits on land that was formerly the site of an ancient temple dedicated to the Roman god Mercury.
Perpetual Adoration of the Blessed Sacrament has occurred here without interruption since August 1, 1885.
The Basilique du Sacré-Cœur is a Roman Catholic minor basilica located at the highest point of Paris on the Butte Montmartre. Its distinctive white exterior is composed of travertine stone that secretes calcite, ensuring the building whitens further with age and exposure to pollution. Designed by architect Paul Abadie in a Romano-Byzantine style, the structure features a 83-meter-tall dome and a massive bell tower housing the 'Savoyarde,' one of the world's heaviest bells. Construction began in 1875 to fulfill a national vow following the Franco-Prussian War and was officially consecrated in 1919. The interior is dominated by one of the world's largest mosaics, titled Christ in Majesty, which covers 475 square meters of the apse ceiling. Beneath the basilica lies a large crypt containing relics and the hearts of several prominent figures. The site remains an active place of perpetual adoration, a practice of continuous prayer that has been maintained since 1885.
The grassy slope of the Square Louise Michel directly in front of the basilica offers the best perspective of the building's facade.
Visit the dome observation gallery for an unobstructed 360-degree view of Paris.
Respect the silence required for prayer in the main nave, as this is an active place of worship.
Access the crypt area for a quieter, more historical perspective of the basilica's foundation.
Avoid the heavy concentration of street performers and aggressive souvenir vendors immediately surrounding the steps at the base.
Visitors are expected to dress modestly, covering shoulders and knees. Silence must be maintained in the interior during prayer services.
