{{Main|Austrian State Treaty}}
The four-power control of Vienna lasted until the [[Austrian State Treaty]] was signed in May 1955 and came into force on 27 July 1955. By October, all soldiers had left the country. That year, after years of reconstruction and restoration, the [[Vienna State Opera|State Opera]] and the [[Burgtheater]], both on the ''Ringstraße'' reopened to the public.

In the Autumn of 1956, Vienna accepted many Hungarian [[refugee]]s, who had fled Hungary after an [[Hungarian Revolution of 1956|attempted revolution]]. The city experienced another wave of refugees after the [[Prague Spring]] in [[Czechoslovakia]] in 1968, as well as after the [[Breakup of Yugoslavia|collapse of Yugoslavia]] in 1991.

In 1972 the construction of the ''[[Donauinsel]] and'' the excavation of the [[New Danube]] began. In the same decade, [[Chancellor of Austria|Austrian Chancellor]] [[Bruno Kreisky]] inaugurated the [[Vienna International Center|Vienna International Centre]], a new area of the city created to host international institutions. Vienna has regained much of its former international stature by hosting international organisations, such as the United Nations.
