A short calle (a Venetian lane) branching off Campo San Lio, in the sestiere (district) of Castello, beside the church of San Lio, running north to the Rio del Piombo, where the Ponte del Pistor connects it to Calle del Pistor. The rio was formerly called del Brusa Piombo, after the lead founder who had his works there in the 16th century.
