A bank is a financial institution that accepts deposits from the public and creates credit.
The Italian Assassin Ezio Auditore da Firenze was able to use banks to view the total percentage of Rome or Constantinople's renovation, as well as withdraw any income from investments that had been deposited into the banks' vaults.
In the 15th century, banks could be found throughout the cities of Florence, San Gimignano, Forlì, and Venice. Each bank was usually guarded by three or four guards. Banks could only be looted once and typically only contained florins. Some banks, always guarded by Borgia guards, held in addition Codex pages, which could be taken and brought to Leonardo da Vinci to be decoded.
Banks contained two chests, and while they were always guarded, more guards usually patrolled nearby. Rebecca Crane once stated that although all families owned banks, most of them were under the control of the Pazzi family, and that breaking into them would be worthwhile. In truth, the banks' guards ceased to wear the colors and emblems of the Pazzi after the destruction of the Pazzi conspiracy.
In the 16th century, there were ten banks scattered throughout the districts of Rome, which, once renovated, would increase the limit of florins that could be stored within the banks' vaults. In addition, renovating them would boost the amount of income generated over time.
Similarly to the money chest in the Monteriggioni villa, the banks carried a limit to the amount of florins they could contain, and would not deposit any additional income once full.
- The maximum amount that could be stored in Rome's bank vaults was 80,000 florins, while in Constantinople it was 120,000 Akçe.
- Before the execution of his father and brothers, Ezio was apprenticed to become a banker, as his father and older brother before him.
- In modern day Monteriggioni, the bank was the only building that had retained its purpose since the Renaissance; however, the sign above the entrance stated it had been rebuilt and re-established in 1802, centuries after its destruction during the Siege of Monteriggioni.
