Transfer to Frankfurt

These are a few selected sites you can see in the German City Frankfurt am Main.

Römerberg
Römerberg is the old centre of Frankfurt, with a number of historic buildings dating to the 14th and 15th century (many of which, unfortunately, were destroyed during World War II and rebuilt afterwards). The Römer itself is the town hall of Frankfurt. Next to the cathedral, at the Archäologische Garten, you can see the remains of the Roman settlements that gave this place its name. At the Römer, you can also visit the Alte Nikolaikirche (a 12th century church, taking its current form in the 15th century). Several restaurants, cafés and smaller shops can be found at the square itself and in the vicinity. Walking towards the Main river, you approach the Eiserne Steg, a 19th century bridge leading to Sachsenhausen, as well as the Rententurm (Wharfinger's Tower), a 15th century fortified tower in late Gothic style, connected to the Saalhof, an old 12th century castle building that was later modernized but never completely destroyed.

Saint Bartholomeus' Cathedral (Dom)
The main cathedral, built in Gothic style in the 14th century on the foundation of an earlier church. From 1562 to 1792, emperors of the Holy Roman Empire were crowned in the cathedral. It is possible to ascend the spiral stairs of the 95 metre church tower.
 

Iron Bridge (Eiserner Steg)
Frankfurt's most well-known pedestrian bridge, built in 1869. It is just a minute away from the Römer, and provides great views of the skyline and the Main river. On the other side, you will reach Sachsenhausen, a district known for its museums and historic pubs.

Hauptwache
A public area that is often considered the central hub of Frankfurt's modern city centre area due to its importance as a public transportation station as well as its central location, right between the main shopping street (Zeil), the Rossmarkt (another public square), and the Eschenheimer Tor. The place is named after a Baroque building ("Hauptwache") located more or less in its centre. The building was constructed in 1730 to house the local city militia, as Frankfurt was an independent city at the time. When Frankfurt became part of Prussia, the building gradually lost its original function. Since 1905, it has instead been serving as a café ("Café Hauptwache"). Other attractions include the Katharinenkirche (an old church), and the Palais Thurn-und-Taxis (an 18th century palace partially rebuilt 2004-2009).

Alte Oper Frankfurt
Alte Oper (Old Opera), Opernplatz 1 (take U6 or U7 station Alte Oper, or any line to Hauptwache and walk a few minutes), Renaissance Opera Building in the center of the city, on a busy square with fountains and cafés. Originally opened in 1880, it is not used for operas any more since the rebuilding after the war, but for concerts, congresses, and similar "fancy" events.
