Park Güell Hypostyle Hall, Barcelona, Spain

Believe the hypostyle

It sounds like the name of some futuristic fashion fad, but the term 'hypostyle' really comes from ancient Greek. It refers to a large hall with a column-supported roof, in this case a ceiling covered in tiny tiles and intricate mosaics. The Hypostyle Room is the apter of two names given to this pavilion in Park Güell, Barcelona, designed by Antoni Gaudí in the early 1900s. Its other name, the Hundred Columns Chamber, is catchy but inaccurate: The always-unorthodox Gaudí removed columns from the regular pattern to create a more open feel, so there's just 86 of them.
