Suffolk County Jail
Also known as: Charles Street Jail
Why it's listed
Built between 1848 and 1851 on landfill beside Massachusetts General Hospital, the Suffolk County Jail on Charles Street in Boston is a granite-faced masonry building with a cruciform plan. Four four-story wings radiate from an octagonal central core, and the exterior shows rusticated granite, round-headed window arches and Renaissance-inspired detail. Gridley J.F. Bryant designed it, working with prison reformer Rev. Louis Dwight. Its layout followed the Auburn Plan, which favored cells for sleeping only, with communal work and exercise, over solitary confinement. The design also provided sunlight, a ventilating system and separate wings for different classes of inmates. Contemporary guidebooks reported that other jurisdictions adopted the plan, and an English magazine published it in 1849. The north wing was enlarged in 1901 and the west wing in 1920, both copying the original design. The jail is recognized as a leading example of Boston granite architecture and of reform-minded penology.
Significance in brief: The nomination calls it the prime institutional example of the Boston Granite Style of the mid-19th century, designed by one of that style's foremost exponents. It also argues the jail is the definitive example of an enlightened 19th-century attitude toward prisoners, built on the Auburn Plan with communal exercise yards, natural light and ventilation. Its design influenced other prisons, including H.H. Richardson's Allegheny County jail.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
