Springfield architect William Devlin will lead a walking tour in the Quadrangle-Mattoon Street area on Saturday, May 14, from 10:30 a.m.-noon.

Devlin will discuss how buildings in the area have evolved through the years, from simple changes like filling in windows to major additions. He will point out the distinctive features of the George Walter Vincent Smith Art Museum, the Classical High Condominium, and the Verizon building on the corner of Dwight and Bridge streets. Devlin is a member of the American Institute of Architects and is on the board of the Springfield Preservation Trust. The tour is part of the Second Saturday Walking Tour series, co-sponsored by the Armoury-Quadrangle Civic Association and the Springfield Museums. Walking tour tickets may be purchased in the museum Welcome Center at 21 Edwards Street on the day of the event. Tickets are free for members of the civic association or of the museums. Tickets for non-members are $5 per person. All proceeds will go toward improvements to the neighborhood. The walking tour ticket will also provide $2 off the price of an adult admission to the Springfield Museums on the day of the tour.
