The former church and monastery of Saint Basil (San Basilio) was also known as the Armenian church because in the Fourteenth century it was kept by Armenian speaking Basilian monks. Following a dwindling presence of the monks, the buildings were passed on to the Congregation of the Priests of the Holy Spirit (1491) who were especially involved in helping sick or destitute priests. The terracotta glazed tondo by the della Robbias  with a white dove that can still be seen on the Church on the via San Gallo side, recalls the emblems of the Congregation that was in fact disbanded in the late 18th century. The Church was no longer used for worship but maintained its outer appearance in spite of different uses.

In 1882 the Methodist Episcopalian Church obtained the premises and renovated them. The façade can be seen in a sketch by Paolo Paschetto, an artist who drew it for the book ‘Cenni storici della chiesa metodista episcopale’ (History of the Methodist Episcopalian Church)  (1895). In 1939,  the building was passed to the Seventh Day Adventists, a church founded in the United States and in Italy in the second half of the Nineteenth century. It joined Tuscany’s Protestant world in the early 20th century and in 1912 its first place of worship in Florence was inaugurated. Currently,  the Rumanian speaking Seventh Day Adventist congregation is in via S. Gallo, while another congregation is in the new premises in the in Careggi District, in via del Pergolino, 1.
