Sainte-Trinité, Paris Information (Geography)
The Église de la Sainte-Trinité is a Roman Catholic church located in the 9th arrondissement of Paris. The church is a building of the Second Empire period, built between 1861 and 1867 at a cost of almost 5 million francs.
La Trinité, as it is known, was designed by Théodore Ballu as part of the beautification and reorganization of Paris under Baron Haussmann. Exterior figures of Faith, Hope, and Charity on the church were sculpted by Eugène-Louis Lequesne. The 93 meter-long church has a bell tower 63 metres high topped by a dome. The choir is ten steps higher than the nave and surrounded by an ambulatory.  Also named after it are the rue de La Trinité and the square de La Trinité.
The church is accessible by the Métro (the nearby station, Trinité, is named after it) and is known internationally for its former organist, the French composer Olivier Messiaen. It was the location of Gioachino Rossini's funeral, on 13 November 1868, Hector Berlioz's funeral, on 11 March 1869, and Georges Bizet's funeral in 1875.
La Trinité features two organs, a Cavaillé-Coll chancel organ and a Cavaillé-Coll grand organ located in the balcony. The latter instrument has been extensively renovated and expanded over the decades:
- 1869 Original construction by the Cavaillé-Coll firm
- 1871 Reconstruction and repairs by the Cavaillé-Coll firm after damages incurred during the Paris Commune of 1870
- 1901 Rebuilding by Merklin
- 1934 Rebuilding by the Pleyel-Cavaillé-Coll firm
- 1962–65 Rebuilding by the Beuchet-Debierre firm
