Great panorama. Ism't it a Prague Castle? "The largest castle complex in the world, this vast fortress requires considerable time to tour, but it's time well spent (particularly rewarding are the excellent views over the Vltava River with the old town and its many beautiful spires in the background). Highlights include the Old Royal Palace's main hall, the Vladislav Hall, so large it could be used for jousting tournaments, and staircases wide enough to allow mounted knights to use them." source:http://www.confiduss.com/en/jurisdictions/czech-republic/
