In the 1960s and 1970s, a new vision for a vibrant downtown materialized through a series of structures that remain today as an enduring imprint of the modern era in Springfield. Join us as we examine the buildings that redefined the downtown experience, from the elegant minimalism of SOM’s Credit Life Tower to the sleek expressionism of Alfred Shaw’s Key Bank Building. Meet at the corner of North Limestone and East Main Streets. $15, which includes one drink at Seasons Bistro and Grille. Guided by Suzanne Cavazos. Sponsored by Julie and Joe Garrigan. Mobility 1.
