Born in
Alessandria in 1901, Ganelli moved early with his family to
Rome, where he studied
civil engineering. After graduating in 1924, he settled in
Grosseto, Tuscany, where he became a key figure in the city's urban development between the 1920s and 1950s. His early work in
Maremma included urban redevelopment projects in
Follonica, where he served as municipal technical director, and the construction of the "Luigi Pierazzi" seaside colony. In 1931, he designed the Francini clinic in Grosseto, notable for its eclectic
neo-Renaissance style. He developed a strong collaboration with the
Diocese of Grosseto, designing almost all new churches in the area from the 1930s to the 1950s. Major works include the churches of
San Giuseppe,
Medaglia Miracolosa,
San Giuseppe Benedetto Cottolengo, and the monumental
Basilica of the Sacred Heart of Jesus, built to commemorate the victims of the
1943 bombings. In addition to religious architecture, Ganelli contributed to civic and social projects, including schools, orphanages, healthcare facilities like the OMNI building, sanatoriums in Grosseto,
Massa Marittima, and
Orbetello, as well as public housing in
Castel del Piano and Bagno di Gavorrano. Ganelli died in Grosseto in 1985 and was buried in the
cemetery of Misericordia. ==Works (selection)==
