Entrance to the old square. There is the town hall called Römer on it.
Town hall and a Themis statue in front of it.
Eagle and an EU flag in front of the town hall.
Alte opera - the opera house.
The famous "Hammering man" in front of the Messe-tower, the highest building in Frankfurt. They didn't allow us to visit the top of it. There are no tourist excursions anymore after 9/11.
The twin towers of Deutschebank.
Haupamt means "main institution". In German, they usually specify the kind of an institution, but here it seems to be just main and, presumably, the most important one :)
Europaturm, the TV tower in Frankfurt. No excursions here either.
