The Loggia of Bigallo, built in the mid 14th century for the Compagnia della Misericordia together with the neighbouring oratory, became in 1425 the seat of the Compagnia del Bigallo, named after the hospital it directed at Santa Maria a Fonteviva that was known as Hospital of Bigallo.
The works directly purchased by the Brotherhood or donated to it, dispersed due to several vicissitudes, were reunited in this museum in 1904.
The collection, reorganised in 1976, comprises both religious and historical works that offer us further evidence on the life of the Brotherhood between the 14th and 16th centuries. The most remarkable pieces are the Crucifix of the "Master of Bigallo", the works of Bernardo Daddi and his pupils and those of Niccolò di Pietro Gerini.
In addition to paintings, the collection displays also some important sculptures like those of Alberto Arnoldi (mid 14th century) who also sculptured the niches and loggia.
