The Hungarian State Opera House is located on Andrassy Avenue. The Italian neo-renaissanse-style building is famous for its elegance and outstanding performances. During the year grand events such as balls are also held here.

Andrassy Avenue is 2,5 kms long, and it connects the city center with Heroes' Square. The 3rd oldest underground railway line in the world (after NY and London) runs beneath this avenue.

The dome of St. Stephen's Cathedral has the same height (96 m) as the dome of the Parliament. Our first king's (St. Stephen) holy right hand is exhibited in this cathedral.
