Dulwich Picture Gallery in London is hosting only its second-ever photography exhibition, and this one charts American cities as they shifted through decades of profound social, cultural, and economic change. The exhibition opens in the early 1900s, a moment when American cities expanded rapidly through mass immigration, industrial growth, and new forms of labor — drawing photographers to sites of social and economic shift. The exhibition then turns to artists documenting the dramatic physical changes reshaping American cities in the mid‑20th century. Moving into the 1960s and 1970s, the exhibition explores how photographers responded to a nation undergoing cultural and political transformation. Portrait of a City: A Century of American Photography opens at Dulwich Picture Gallery July 28 – October 4, 2026.
