The 20th century was a turbulent one for Estonia's currencies. This modern museum displays every kind of banknote used here from Tsarist roubles to German occupation tender, and outlines the history of Estonia's national bank itself, founded in 1919. There's also an in-depth exhibit that helps the visitor understand the role of money in society and information all about the Euro and just how the Eurozone works. For anyone who's already forgotten what they look like, those now-extinct Euroland currencies (the Estonian Kroon included) are also showcased.
