On a sunny summer day in Chicago, visitors to the Chicago Architecture Center had only to cross busy Wacker Drive to board the tour boat that would take them past the architectural icons that line the Chicago River. On board , docents pointed out landmarks such as the white terra cotta Wrigley Building completed in 1924 and the corncob-shaped Marina City towers from 1967 designed by Bertrand Goldberg.

The Instagrammable itinerary, ranked as the city’s top attraction on TripAdvisor, has long been the most popular offering from the nonprofit formerly known as the Chicago Architecture Foundation. With last fall’s move eight blocks north to One Illinois Center, to a building designed by the modernist architect Ludwig Mies van der Rohe, the renamed Chicago Architecture Center gained a prominent riverfront location and a platform to tell the story of Chicago design and its global influence.

“We’re opposite the cruise dock, in the last building Mies designed on the site of Fort Dearborn where the city was founded,” said Lynn Osmond, the president and chief executive of the Chicago Architecture Center, emphasizing its centrality, both geographically and historically.
