I wore a #Bitcoin t-shirt during my visit of the Château of Chenonceau.

Catherine de Medici once lived here.

The Medici family had one of Europe’s largest banks and is said to be an early adopter of the double-ledger accounting systems.

If anyone has more info, please share in the comments!

“The Medici Bank, from when it was created in 1397 to its fall in 1494, was one of the most prosperous and respected institutions in Europe, and the Medici family was considered the wealthiest in Europe for a time. From this base, they acquired political power initially in Florence and later in wider Italy and Europe. They were among the earliest businesses to use the general ledger system of accounting through the development of the double-entry bookkeeping system for tracking credits and debits.”
