Norfolk County Courthouse
Also known as: Sacco-Vanzetti Trial Site
Why it's listed
Norfolk County Courthouse, at 650 High Street in Dedham, Massachusetts, is a granite Greek Revival building completed in 1827 by Boston builder Solomon Willard. It began as a rectangular structure with pedimented porticos at each end. Wings flanking the north portico were added during the Civil War period, along with an earlier dome. Between 1892 and 1895, plans by the Boston firm of Gridley J.F. Bryant added wings beside the south portico, giving the building its H-shaped plan, and replaced the earlier interiors with Greek-inspired motifs in golden oak and marble. The courthouse is best known as the site of the 1921 trial of Nicola Sacco and Bartolomeo Vanzetti, who were convicted of a 1920 payroll robbery and murders and executed in 1927. The case became an international cause and exposed divisions in American society. The second-floor courtroom, with its pale-pink walls, coffered ceiling and original furnishings, remains largely as it was during the trial.
Significance in brief: The courthouse is the setting of the 1921 Sacco-Vanzetti trial, which the nomination describes as a case that crystallized the tensions of the 1920s and drew world attention. The building has remained largely unchanged since the trial, so its courtroom and exterior still evoke that event.

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.
