Former County Jail, featuring 18 cells with imposing limestone walls (15 feet high and 2½ feet wide). Until 1974, it was used as a Napanee Town Police lockup. In 1976, the Lennox & Addington County Museum & Archives took over the building, and in 2014 it underwent an archives wing expansion along with restoration to the original building. Today, the museum provides insights into everyday life from the late 18th to the 20th century, with its primary focus being to tell the story of Lennox & Addington County. The museum houses a research library, a collection of approximately 10,000 artifact items, local archives documenting county history, and genealogical files for those who want to find their personal connection to the past.
As an active museum, filming is restricted around exhibition placements. The museum does have two visible jail cells fully accessible for filming.
