How much was the Basilica of Sacre Coeur to build?

The Basilica of Sacré-Cœur in Paris was constructed between 1875 and 1914, with an estimated cost of around 7.8 million francs at the time. Adjusted for inflation and considering the historical context, the total cost would be significantly higher today. Funding primarily came from public donations, as well as state and church contributions. The basilica remains a symbol of both religious devotion and national reconciliation following the Franco-Prussian War.
