The Arsenal was the Shipyard of Venice . The Byzantine-style establishment may have existed as early as the 8th century, though the present structure is usually said to have been begun in 1104, although there is no evidence for such a precise date. It definitely existed by the early thirteenth century and is mentioned in Dante's Inferno. The name probably comes from Arabic Dar al Sina’a ("Dockyard") and the concept was clearly Islamic as much as Byzantine.

Initially the state dockyard worked merely to maintain naval ships built privately, but in 1320 the Arsenal Nuovo was built, much larger than the original. It enabled all the state's navy and the larger merchant ships to be both constructed and maintained in one place. The Arsenal incidentally became an important centre for rope manufacture, while housing for the arsenal workers grew up outside its walls.
