Mechanics Hall, Boston
Mechanics Hall (or Mechanic's Building) in Boston was a huge hall, kind of like what we think of as a convention center. Many events took place there, including those related to suffrage.
It was the final stop for the huge suffrage "Victory" parade on October 16, 1915. The parade was reviewed by Gov. David I. Walsh, and Mayor James M. Curley. After the parade, suffragists held a mass meeting there that lasted two hours. Mayor Curley and others spoke. The Boston Globe's headline for its story of the event said "Mass Meeting A Huge Affair. Eight Thousand Hear Suffrage Orators. Overflow of 2000 Outside of Mechanic's Building. Mayor Praises the Women for Their Showing." Boston Globe, October 17, 1915, p11.
This was also the final stop for Pres. Wilson during his visit to Boston on February 24, 1919. Protests earlier in the day by militant suffragists resulted in the arrest and imprisonment of up to 24 women suffragists. Boston Globe, February 25, 1919.
Mechanics Hall was on Huntington Avenue at Norway Street (approx. West Newton Street), not far from suffrage organization headquarters at 585 Boylston Street, across from Copley Square and the Boston Public Library.
The building lasted from 1881 to 1959. Find more good information about it at Wikipedia, Lost New England, and And This Is Good Old Boston. A good photo of the interior from 1949-1950 is here.
