Nostra Signora del Sacro Cuore, Catholic church in the historic centre of Florence, Italy

Nostra Signora del Sacro Cuore is a neoclassical church in Florence whose facade was left unfinished: two isolated columns stand where a portico with a large pediment was planned. Inside, eight monolithic columns with Corinthian capitals, cut from the quarries of Monte Ceceri, line the nave. The building stands on Piazza Santa Caterina d'Alessandria, at the corner of Via Enrico Poggi.

Construction began in June 1848 on a design by Gaetano Baccani for the Barbano district, but funds ran out and work stopped. In 1857 Giuseppe Martelli took over, added side aisles and used ten monolithic columns quarried at Monte Ceceri. The church opened for worship on 31 December 1863, dedicated to the Immaculate Conception and Saint Catherine of Alexandria; the Missionaries of the Sacred Heart bought it in 1904 and it became a parish in 1937.

The church serves the local community as a place for regular Catholic worship and belongs to the network of the Roman Catholic Archdiocese of Florence. It shapes religious life in the area and draws worshippers from the surrounding neighborhood.

The church is accessible by public transportation, with several bus stops within walking distance of the entrance. Visitors should note that regular services take place and it is best to arrive during the scheduled times offered.

The ten monolithic columns already prepared for Gaetano Baccani's 1848 project were reused by Giuseppe Martelli in 1857; they came from the quarries of Monte Ceceri. The planned three-arched portico with a neoclassical pediment was never built, leaving two isolated columns on the unfinished facade.
