After the collapse of the Nazi regime, the stock exchange in Frankfurt was closed for six months, and reopened in September 1945. Today it is one of the largest stock exchanges in the world. You can see the trading floor on the rounds that run Monday through Friday. For 125€ you will get a great presentation including the history of the stock exchange, be sure to ask for English if you need it. Outside the beautiful colonnaded building, see two bronze figures, a bull and a bear, which represent the rise and fall of the world's stock markets.
