The town of Thompson is located in Windham County in the northernmost part of the state and borders on Massachusetts to its north and Rhode Island to its east. Named after English landholder Sir Robert Thompson, the town incorporated in 1785. In 1891, the Great East Thompson Train Wreck, one of the worst railway collisions in US history and the only one to involve four trains, took place within the town’s borders. Thompson is the birthplace of Ithiel Town, one of the nation’s most celebrated early architects and, while it cannot be proven, residents believe that he designed the Old Town Hall building that served the community for 80 years and is now the location of the Thompson Historical Society.
