The Basilica of the Sacred Heart (in French, basilique du Sacré-Cœur) is a temple of the Roman Catholic Church in Paris, and is also the symbol of the neighborhood of Monte Martre. The basilica is located at the top of Mount Martre, the highest point in the city. The Basilica of the Sacred Heart was built with travertine marble extracted from the Seine-et-Marne region, which gives it a white hue.
One of the most visited monuments of France, the basilica has the shape of Greek cross adorned by four domes, including the central dome of eighty meters high. In the apse, a tower serves as a steeple to a bell of three meters in diameter and of more than 26 tons.
The architecture of the basilica is inspired by Roman and Byzantine architecture and influenced other religious buildings of the twentieth century.
