Baseball stadiums don’t generally have the architectural cachet of, say, museums or skyscrapers. But if you consider how many people are directly affected by the design of a building, it’s hard to top baseball parks in the civic impact department. Washington, D.C. has a new baseball team, of course, and will shortly have a new park to keep it in. The question is, how will the design of the ballpark affect the city, and vice versa? “The park represents a giant architectural and planning opportunity for the nation’s capital, a rare chance to build a splendid, 21st-century ‘gateway’ structure near a major bridge and within site of the Capitol dome. And to help revive a river and a section of the city.”
