L'Eglise de la Sainte-Trinité is the larger of the two churches. It was built in six years' time in the 1860s when the Baron Haussmann decided to relocate an older church of the same name to the present site. The building is 90 meters (295 feet) long and the bell tower is 65 meters (213 feet) high.
I've still never been inside the Trinité church, even though I've walked past it hundreds of times, especially during the years when I was commuting on trains in and out of the Gare Saint-Lazare.
The statues on the four corners of the bell tower represent saints Matthew, Mark, Luke, and John.
One of the church's claims to fame is that the funeral of the composer Hector Berlioz was held here in March 1869. The façade is decorated in Italian Renaissance style, with elements of Gothic and French Renaissance architecture. An iron and steel framework, while nowhere visible, reinforces the structure.
I like the way the face on the left side of the photo seems to be peering down over the wall of the tower.
The other church in the neighborhood is the Eglise Notre-Dame de Lorette. I took some photos there too...
