Reconstruction of City Hall lasted from 1873 through 1892 (19 years) and was directed by architects Théodore Ballu and Édouard Deperthes, who had won the public competition for the building's reconstruction. Ballu also designed the Church of La Trinité in the 9th arrondissement and the belfry of the town hall of the 1st arrondissement, opposite the Louvre's east facade. He also restored the Saint-Jacques Tower, a Gothic church tower in a square 150 metres to the west of the Hôtel de Ville.
