Magnificent views, of course, but it also offers a masterclass in key episodes of 19th- and 20th-century Hungarian history
Habsburg Fortress, Highest Point in the City
The highest point in all of Budapest is atop Buda's Gellért Hill at the Citadel, built between 1851-1854 by the Habsburg rulers -using forced labour- to keep an eye on the city after a revolutionary uprising. During World War II it was used as a bunker, then by the Soviets in 1956 to quell the Hungarian uprising against them. Head up here from either the Erzsebét (Elizabeth) Bridge or Szent Gellért Square and you'll be greeted by some stupendous views out over the city. You'll also find several restaurants, market stands, a monument to liberation from the Nazis and the fortress itself, which is relatively low-standing with walls four metres (13 feet) high, but which are 220 metres (722 feet) long and 60 metres (197 feet) wide. The three-storey building today houses wax figures illustrating key episodes of World War II - an interesting way of learning about Budapest's experience of this traumatic conflict. The fortress closes for the day at 19:00.
