The Cathedral of Grosseto, named after San Lorenzo, is the city's most important monument.
As an inscription on the right-end side of the facade attests, the Cathedral was built beginning in the late 13th century under the direction of master Sozzo Rustichini, who also participated in the construction of the facade of the Cathedral of Siena.
The interior houses interesting works of art, such as the imposing marble baptismal font by Antonio Ghini and, also by the same author, the sculpted frame of the Altar of the Virgin Mary that houses the precious panel painting by Matteo di Giovanni.
The atmosphere created by the beams of light from the Gothic windows on the right wall, the work of Benvenuto di Giovanni, a 15th-century artist from Siena, is very striking.
The Cathedral is fully accessible, and inside there is a tactile path for the blind and visually impaired: thanks to special tactile tables, it is possible to learn about reproductions of the plan of the Cathedral, the painting of Our Lady of Grace, the baptismal font, the facade of the Cathedral, the Crucifix by the Vecchietta, and the stained glass windows with saints by Benvenuto di Giovanni.
Qr-codes with information about the Cathedral, Our Lady of Grace and other works have also been included in each tactile table.
