Royal Palace
A World Heritage Site, Buda Castle (or Royal Palace) is one of the most emblematic architectural masterpieces of the city.
The former Royal Palace has been razed and rebuilt at least half a dozen times over the past seven centuries. Béla IV established a royal residence here in the mid-13th century, and subsequent kings added to the complex. Today, the Royal Palace houses the Hungarian National Gallery, the Budapest History Museum, and the National Széchenyi Library. It's a scenic location. No doubt why it's been used as a background in many films and videos. E.g. Katy Perry's music video "Firework" was shot in the courtyard of the Royal Palace. If you are eager to culture, visit the palace's courtyards during the Wine Festival in September or the Festival of Folk Arts on the 20th of August. Taste a traditional wine or return back home with an artisan souvenir from the festival.
