It was Cosimo I de' Medici’s idea to build a shipyard in Pisa for the vessels of the powerful Tuscan fleet. It was part of a wider scheme to restore Pisa to its ancient splendour, after its fall into disrepair following surrender to Florence in 1509.In 1562 the Order of Knights of St. Stephen was instituted, it too, with the shipyard designed by Buontalenti, was part of this plan. By 1540 it was already fully operative, and in 1546 this new shipyard built by the Medicis launched the first galera to be constructed entirely by local craftsmen.The shipyard was constructed in eight aisles, each roughly 60 metres long, 8 metres high and 10 metres wide. Soon the yard had to be enlarged.
