Turbine Hall

Tate Modern has one hell of an entrance lobby in the form of the Turbine Hall: a vast, cathedral-like space that occupies nearly the entire ground floor of the building. It plays host to a series of commissions from some of the world's most prominent artists (formerly sponsored by Unilever, now by car giant Hyundai). The hall has seen highs and a couple of dismal lows – but standouts include Olafur Eliasson glowing, sun-like orb of light and Louise Bourgeois's gargantuan spider.
