Located on the historic Heldenplatz ,this is were Adolf Hitler made his infamous speech in 1938,Austrian Anschluss to Nazi Germany,is Neue Burg.
Neue Burg is now a series of museums and looks amazing ,constructed over the 19th & 20th century ,the Neue Burg ( New Palace ) is in my opinion one of the standout buildings here ,it's very photogenic and most definitely well worth checking out if you're planning a holiday to Vienna and easy to locate on Heldenplatz.
