Top choice historic site in Castello

Founded in 1104, the Arsenale soon became the greatest medieval shipyard in Europe, home to 300 shipping companies employing up to 16,000 people. Capable of turning out a new galley in a day, it is considered a forerunner of mass industrial production. Though it's closed to the public most of the year, arty types invade the shipyard during Venice's art and architecture Biennales, when it hosts exhibitions and special events.
