Funded by Charles E. Chaffee, the Windsor Locks Memorial Hall was erected as the gathering place for the Grand Army of the Republic’s Post No.67, an organization for Union veterans. The group’s official name was the JH Converse Post, dedicated to fallen soldier Joseph H. Converse. When local deacon Jabez H. Hayden sold the land to the GAR, he included a clause stating the land must be used as a soldier’s memorial forever or turned over to the town’s orthodox congregational church. This clause has facilitated the continued preservation and use of the building as a meeting hall for veterans today. On the last Sunday of each month, guided tours are offered to allow exploration of the building and its history.
