Thompson Square was a rapid transit station on the Charlestown Elevated, part of the MBTA's Orange Line. It opened on May 22, 1902 - almost a year after the rest of the Charlestown El - as an infill station. It was closed in 1975, when the line was rerouted into a tunnel that was constructed as part of the Haymarket North Extension project.The station was lowered to the ground, with plans to reuse the structure as a restaurant, but it was destroyed by fire on April 19, 1976, before the conversion could be done.
