The Neue Nationalgalerie (New National Gallery), the 'temple of light and glass' designed by Mies van der Rohe, houses a collection of 20th century European painting and sculpture. It’s main exhibition spaces are below street level. The building comprises almost 5,000 square metres of exhibition space and around 800 metres of wall space – a surprisingly large capacity hidden half underground beneath the famous steel and glass construction. The spacious glass hall at ground level lures the visitor inside, underneath the great black structural steel canopy. Along with Mies’ Barcelona Pavilion, the Neue Nationalgalerie is considered one of the foremost examples of structural abstraction emblematic of the International Style.
