Old St. Helena Parish Jail

The brick jail on Greensburg's courthouse square opened around 1855 and held prisoners for nearly a century — one of fewer than five mid-nineteenth-century jail buildings surviving in Louisiana when it was listed on the National Register in 1980. The cells remain, bars still fixed in the windows. Today it operates as a local history museum, documenting law enforcement and community life in a courthouse-square town that has changed little since the timber era ended. The museum tells that story best. Open limited hours; call ahead.
