Free Walking Tours in Frankfurt focus on the charming old town and the structures that survived after the Second World War. Incredibly, the Imperial Cathedral, the Romerberg Square, and the Romer (City Hall) all date back to the Middle Ages! The Imperial Cathedral is a Gothic-style Roman Catholic church with an impressive 95-meter-tall spire! Polymath Johann Wolfgang von Goethe was born in Frankfurt, so you can visit his childhood home. The house is filled with contemporary artifacts, such as an astronomical clock. Along the river, you'll find Museumsufer, a cluster of some of the best museums. But, Frankfurt is also a city where new and old meet. Head to the riverside late in the afternoon and walk across Frankfurt’s elegant Ironbridge as the sun hits the sea of skyscrapers in Bankenviertel. You'll understand why this area is called 'Mainhattan'!
