Stadia: Sport and Vision in Architecture, at Sir John Soane’s Museum in London, examines the evolution of stadiums and how architects have used the typology, from antiquity onward, to push innovation. (Rome’s Colosseum inspired Soane himself.) Populous, the firm behind the 2012 Olympic Stadium, shown, sponsors the exhibit, and posits that the stadium is the new cathedral, putting towns and cities on the map. To top it all off, “Stadia” is also the inaugural show in the museum’s new temporary exhibition space, renovated by Caruso St. John Architects. Through Sept. 22. • soane.org
