It was a location for debates among anarchists, socialists, and union leaders over the future direction of the labor movement in the United States in the early 20th century.

The direct association of this property with the labor movement, community, and the immigration of Italians makes it one of Barre's most important buildings.

The most important of these is a carved medallion depicting an arm bearing a hammer, the symbol of the Socialist Labor Party, and the initials SLP.

Labors leaders such as Eugene Debs and Samuel Gompers are known to have visited Barre and, although unconfirmed, likely spoke at the Hall.

During one political gathering in 1903, illustrating the sometimes volatile nature of political groups at this time, an argument broke out between socialists and anarchists, ending in the essentially random but fatal shooting of Elia Corti, a prominent Italian stone carver responsible for the panels on the Robert Burns Memorial statue in Barre.
