• Kaisersaal in the Römer holds portraits of all 52 emperors of the Holy Roman Empire, and coronation banquets were held there from 1612
• Rebuilt after 1944, so most of the old-looking houses are reconstructions and new builds, a good story for kids who ask how old it is
• The Great Angel house (Großer Engel) on the east side of the square is where Frankfurt's first bank was founded in the 17th century

Römerberg is Frankfurt's historic main square. On one side stands the Römer, city hall since the 15th century, with stepped Gothic gables; facing it is the Ostzeile, a row of half-timbered houses, each with its own name.

Kids can spot Justitia on the Justice Fountain, holding scales and a sword without a blindfold. Most buildings are reconstructions: the old town was largely destroyed in 1944.
