The National Theatre, London.

This theatre was designed by architects Sir Denys Lasdun and Peter Softley and contains three stages, which opened between 1976 and 1977: the Olivier Theatre is the main auditorium, which copies the ancient Greek theatre at Epidaurus indoors, with an open stage and fan-shaped seating for 1,160 people. The Lyttelton Theatre has a proscenium-arch and seats 890. The Cottesloe Theatre is an adaptable studio space, designed by Iain Mackintosh, for up to 400. The theatre building overall is an example of Brutalist architecture in England: there is a raw-concrete stress on horizontal and vertical elements which makes the building seem rather like a utilitarian drama factory, so that actors may feel properly proletarian.
