The Bank of Saint George ( or informally as Ufficio di San Giorgio or Banco) was a financial institution of the Republic of Genoa. Founded in 1407, it was the oldest chartered bank in Europe and of the world. The bank's headquarters were at the Palazzo San Giorgio, which was built in the 13th century by order of Guglielmo Boccanegra, uncle of Simone Boccanegra, the first Doge of Genoa.
