Passing along the Via Calzaioli we come on the right to a noble square building with statues in its niches--Or San Michele, which stands on the site of the chapel of San Michele in Orto. San Michele in Orto, or more probably in Horreo (meaning either in the garden or in the granary), was once part of a loggia used as a corn market, in which was preserved a picture by Ugolino da Siena representing the Virgin, and this picture had the power of working miracles.
