Surprisingly this picture was taken from Dorsoduro, at the end of Calle dei Cerchieri.
Calle dei Cerchieri has its other end at Rio de la Toletta.
Cerchieri (cherchiatori in Italian) were coopers or barrel makers. Many had their workshops on this street.
Their confraternity, under the protection of the Virgin Mary, had an altar in the
church of San Trovaso.
