Sacré Coeur Basilica, Montmartre (Basilique du Sacré Coeur de Montmartre)

Designed by the architect, Abadie, who was also responsible for the restoration of St Front Cathedral in Périgueux, work began on the construction of Sacré Coeur in 1875. Abadie, however, died in 1884 and work was not completed until 1914. The white-domed church, which is built in a Roman-Byzantine style, houses one of the world’s largest mosaics designed by the French architect Luc Olivier Merson, depicting Christ with outstretched arms. The domed bell tower contains the Savoyarde, which was cast in Annecy in 1895 and is one of the heaviest bells in the world, weighing in at 19.3 tonnes (19 tons). Today, thousands of visitors climb up the steep steps or take the funicular railway to the top of the Butte de Montmartre (the Hill of Martyrs) every day for the spectacular views across Paris. On a clear day, it is possible to see for 40km (25 miles) from the top of the 112m (367ft) bell tower, which is the highest point in Paris.
