Three crosses in the name, only one in reality — and perhaps not even that: this calle (a Venetian street) in Cannaregio descends from the Fondamente Nuove towards San Canciano, in the old contrada dei Birri, which was not a family but a canal: the Biria, perhaps a corruption of Bierum, the watercourse that drove the mills, buried today beneath the Rio terà dei Birri (a filled-in canal).
