paragraph_text: Architecture for entertainment
  
  Purpose-built structures as venues for entertainment that accommodate audiences have produced many famous and innovative buildings, among the most recognisable of which are theatre structures. For the ancient Greeks, "the architectural importance of the theatre is a reflection of their importance to the community, made apparent in their monumentality, in the effort put into their design, and in the care put into their detail." The Romans subsequently developed the stadium in an oval form known as a circus. In modern times, some of the grandest buildings for entertainment have brought fame to their cities as well as their designers. The Sydney Opera House, for example, is a World Heritage Site and The O₂ in London is an entertainment precinct that contains an indoor arena, a music club, a cinema and exhibition space. The Bayreuth Festspielhaus in Germany is a theatre designed and built for performances of one specific musical composition.
  
  Two of the chief architectural concerns for the design of venues for mass audiences are speed of egress and safety. The speed at which the venue empty is important both for amenity and safety, because large crowds take a long time to disperse from a badly designed venue, which creates a safety risk. The Hillsborough disaster is an example of how poor aspects of building design can contribute to audience deaths. Sightlines and acoustics are also important design considerations in most theatrical venues.
  
  In the 21st century, entertainment venues, especially stadia, are "likely to figure among the leading architectural genres". However, they require "a whole new approach" to design, because they need to be "sophisticated entertainment centres, multi-experience venues, capable of being enjoyed in many diverse ways". Hence, architects now have to design "with two distinct functions in mind, as sports and entertainment centres playing host to live audiences, and as sports and entertainment studios serving the viewing and listening requirements of the remote audience".
