So, what's in store for this year's Heritage Days at the Basilique du Sacré-Cœur? Here's everything you need to know about the 42nd edition!
One hundred and fifty years after it was first built, the Basilique du Sacré-Coeur de Montmartre has been given a new lease of life, with major restorations carried out on its spectacular organ, its legendary 18-tonne bell (the largest in France!) and its high altar. Built in 1898 by Aristide Cavaillé-Coll, the grand organ is one of the largest in Paris and one of the most remarkable in France, and was classified as a historic monument in 1981. Forty years after its last restoration, the instrument is benefiting from major work requiring complete dismantling, which will ensure its long-term preservation and reliability.
