This is the underground station where I got off the subway. The church on the left, Paul's, is famous for being the site of many important political decisions being made/signed.
Frankfurt has a huge cathedral... this shows some of the delicate workmanship.
and in front of the cathedral are remains from an old Roman settlement (maybe 2000 years old? I should google before I post heehee):
This is a view from those ruins toward the marketplace of the city hall. Notice the modern skyscraper in the background?
Another view of the marketplace...
and... once more the Paul's church with the skyscraper background....
