From where we stand, the curved gray and green surfaces of Henry Moore’s Large Arch seem to enfold architect Eliel Saarinen’s First Christian Church. The 1942 building, with its starkly upright, rectangular design, appears much more contemporary than it really is.
Saarinen’s church foreshadowed a revolution instigated by local businessman J. Irwin Miller. In the 1950s, he launched a program to subsidize public buildings with the stipulation that they be designed by great architects. He wanted to foster a world-class community, and he helped fund the investment in the town because he believed that, “Mediocrity is expensive.”
The result is a town filled with more than 70 buildings created by famed architects, giving Columbus (a city of 45,000) a skyline that mixes 20th-century masterpieces with 19th-century structures. That means the anchor of any weekend in Columbus (45 miles south of Indianapolis) should be an architecture tour.
