This is the main altar of el Domo Church with a height of 7 meters, a work of Louis Tullius Joachim Visconti constructed between 1843 y 1853
In order to accommodate the tomb of Napoleón, architect Louis Visconti had to redesign the high altar of the domed church. Upon completion in 1861, the remains of Napoleon's body were then placed in 6 coffins inside a tomb, which was fashioned from red Finnish porphyry with a green granite base, and placed inside the crypt.
