John Adams Courthouse
Also known as: Suffolk County Courthouse

Why it's listed
Rising six stories on Pemberton Square in Boston, this granite courthouse was built between 1886 and 1894 to designs by George A. Clough, the city's first city architect. Clough won the first stage of a design competition and so impressed the County Commissioners that no further competition was held. The building was described at the time as "Modern Classic" or "German Renaissance." In 1909 two floors were added under a high mansard roof, giving it a French Empire look similar to nearby Old City Hall. The plan wraps around open courtyards for light and ventilation. Its chief interior space is the Great Cross Hall, a three-story east-west hall with coffered barrel vaults and corbels sculpted as figures such as Justice, Law and Wisdom. The courthouse represents the monumental public buildings Boston raised in the late nineteenth century, and it remains a pedestrian link between State Street, Government Center and Beacon Hill. It was later renamed the John Adams Courthouse.
Significance in brief: It is one of several major public buildings erected in Boston in the late 19th century, reflecting the Victorian taste for monumental public architecture. It was the major work of George A. Clough, Boston's first city architect. Its design marks an early step from Victorian styles toward Classical Revival, and the 1909 mansard roof gave it a French Empire look. It also has a strong visual relationship with Old City Hall and King's Chapel.

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.
