Sacco and Vanzetti trial at the Suffolk County Courthouse

Nicola Sacco and Bartolomeo Vanzetti were tried for murder in 1921 in the Suffolk County Courthouse (now the John Adams Courthouse) in Boston; their trial, conviction, and 1927 execution generated international protests and enduring debate. The case remains a prominent element of Boston legal and political lore, with historians disputing aspects of the evidence and fairness of the proceedings. The courthouse building continues to house Massachusetts trial courts and preserves records related to the era.
