The Holy Trinity Church is an eclectic temple standing on the right bank of the Seine. It was built in the second half of the 19th century. In his silhouette stands out a polygonal tower modeled on Renaissance, Flemish bales forts. The lower part of the facade with the rosette in turn refers to the Gothic style. The interior of the church is covered with rich polychrome and gilding.
The church was built during the great expansion of Paris during the time of Napoleon III. Together with Opera Garnier and Saint Lazare Train Station it was to be an architectural setting for the district centered around Saint Lazare Boulevard. His designer Theodore Ballu decided that he would break with attachment to one style and create a building that draws on old forms, but mixing them creatively.
In this way, a monumental one-nave church was built, with the body surrounded by chapels. The most characteristic element is the tower decorated with intricate, openwork turrets and decorations. At the bottom of the main facade the motif based on the number 3 is repeated. This is related to the call of the temple. The architect even designed three identical fountains in front of the entrance.
