The Frankfurt Stock Exchange (FSE) is the world's third largest market for stocks, shares and foreign currencies. With a turnover of 75% of all shares traded, it is also the largest stock exchange in Germany. As long ago as the 16th century, several traders made a pact to establish exchange rates for the various currencies coming into the city during trade fairs. This was the forerunner of the FSE. The stock exchange building - a tribute to the High Renaissance style - stems from 1879 when it replaced the old building next to Paulskirche church. Visitors can watch the traders in action from a balcony above the trading floor - a fascinating spectacle. A large screen shows the movements of the DAX (the German share index), while individual share prices can be seen on monitors.
