Venice has a lot of secrets and some have not been discovered yet. Some artefacts have been recycled and inserted into buildings, so it is difficult sometimes to clarify the reason why they are there.
The Hooks at San Canciano
What about the hooks you can see while you are crossing the bridge near Campo San Canciano attached to a wall facing the water? Their meaning might not be clear to all the people who walk past them and kiss them because they think they bring good luck.
The bridge of the Quartered
Those hooks are the only ones left in Venice, There were some more in the district of Santa Croce, at the ponte dei Squartai (the bridge of the Quartered).
They are made out of iron, and have the shape of an anchor like the hooks you find in a butcher shop to hold meat. They were put in at least four different parts of Venice referring to the cardinal points of Padua, Mestre, Chioggia and Lido. Venetian law required that the four parts of criminals’ and traitors’ bodies who had been executed had to be exposed.
