The Littleton Historical Commission (LHC) sponsors several activities to promote the history of the area. Annually the LHC holds a Preservation Workshop at the Old Burying Ground on King Street. This workshop is open to any town residents and provides an opportunity to work with preservation specialists in righting fallen gravestones, repairing broken monuments, and recording and photographing the cemetery's contents. Contact the LHC for dates. The LHC also sponsors the annual Patriot's Day celebration, held at Liberty Square on April 19. Liberty Square was the place where Littleton area residents drilled in preparation for the Revolutionary War. This ceremony, held in the evening on the actual Patriot's Day anniversary, provides an opportunity to reflect on the service of the patriots.
