Columbus, Indiana is an archetypal “middle city” — a mid-sized, Midwest ‘burg in the middle of the country, albeit one distinguished for its exceptional collection of modernist architecture. The future of middle cities is the theme of the third edition of Exhibit Columbus, a biennial celebration and exploration of the city as a laboratory for design and civic investment. We’re joined by Exhibit Columbus director Anne Surak and co-curator Iker Gil to discuss all things middle metropolis — from demographics to technology, climate change, and of course, the pandemic — and what cities have to learn from Columbus.
