Some stunning examples of modern design in Budapest can be found below the surface. To get from the National University of Public Service to the City Center you will have to take Metro line 3. You might then iInterchange to Line 4, which was completed only in 2014, to see the stations Fövám ter and Kálvin ter – which have a more than impressive architecture (pictured below).
If you climb up to Buda Castle (or use the funicular) you will get an overview of the more classical must-sees that Budapest offers its visitors (pictured below). A good chance to see visit Budapest will be the IRSPM conference in 2017.
