Hans Hollein (30 March 1934 – 24 April 2014) was an Austrian architect and designer[1] and key figure of postmodern architecture.

[1] Hollein's early works were small scale designs, such as the Retti candle shop in Vienna, which notably featured a facade constructed of anodized aluminum.

[4] In 1980 he designed the stage for a production of Arthur Schnitzler's drama Komödie der Verführung (Comedy of Seduction) at Vienna's Burgtheater.

The later hasn't been built, but his ideas for an underground museum still materialised in the Vulcania European Centre of Vulcanology in Auvergne in France (1997–2002).

[1] Starting from the late 1990s, Hollein designed large-scale projects, including bank headquarters in Lichtenstein, Spain and Peru.
