4. Budapest is called the Queen of the Danube. The European city proudly wears this name. Some argue that Vienna deserves the title, but Budapest beats it in the category The Greatest Variety of Styles.

The water has a positive effect on the marvelous creatures because the composition is close to that of the Nile basin.

You’ll discover Gothic and Renaissance monuments, as well as Turkish tombstones, in winding corridors and vaulted rooms.
13. No building in Hungary can rise more than 96 m (314.9 ft.). There’s a peculiar reason for that. The regulation takes into account a symbolic number for Hungary.
