The Torri dell Arsenale in Venice, Italy. The Venetian Arsenal (Torri dell'Arsenale) played an important role in Venice's history. The facility, which is identifiable from its twin towers, is said to date back to the 12th century.
Many of the Venetian Republic's commercial and military vessels were built and maintained here. The Venetian Arsenal is a complex of former shipyards and armories clustered together in the city of Venice in northern Italy. Owned by the state, the Arsenal was responsible for the bulk of the Venetian republic's naval power during the middle part of the second millennium AD. It was "one of the earliest large-scale industrial enterprises in history"
