The Sacre Coeur Basilica, or the Sacred Heart of Jesus, stands atop Montmertre. Its white domes are visible from many places in Paris. It is a building from the turn of the 20th century designed in the Romanesque-Byzantine style. Five domes and a towering belfry rise above the central nave.
The basilica was founded after the Franco-Prussian war and the events of the Paris Commune of 1870. On the one hand, it was to be thanksgiving for saving Paris from destruction, and on the other, atonement for the sins of the communists. The church was designed by Paul Abadie using elements of historical Romanesque and Byzantine styles.
The church was built on a Greek cross plan. Above the intersection of the naves there is a central dome 79 meters high. Four miniatures were placed in the corners. A similar dome also covers the soaring belfry. The white color of the whole building is given by travertine used for its covering. The interior of the church is strict. Above the presbytery and in the arms of the transept there are polychromes depicting Merciful Christ. There is a viewpoint on the dome.
