The principal traghetto (ferry) – Piazza San Marco. . Photo by Gribayedoff. "There are nearly twenty ferries across the Grand Canal and the Giudecca. These are the traghetti.. In one sense they are like the cab-stands or cab-ranks of cities built upon land; in another sense they are the unions or guilds of the gondoliers.... In the wooden shelter houses of the traghetti the guild meets and decides all questions of hours of work and choice of station." Source: Outing magazine, vol. LI no. 6, March, 1908, p. 646.
