Osmanlı Bankası Müzesi

The Ottoman Bank Museum is the first museum ever founded by a private bank in Turkey, housed in a stunning 19th-century building designed by architect Alexandre Vallaury right in the heart of Beyoğlu. Inside, you'll find historic documents, cut banknotes, ledgers, and artifacts from the old vault room that tell the story of Ottoman-era finance. It's a surprisingly rich slice of history that most people walk right past.
