The Queen Anne style original structure and Renaissance Revival style Annex are clad in red Philadelphia pressed brick with brownstone trim, and effusively ornamented with unglazed red terra-cotta. Webster Hall has been the venue for countless balls, dances, receptions, lectures, meetings, conventions, political and union rallies, military functions, concerts, performances, festivities, and sporting and fundraising events, particularly for the working-class and immigrant population of the Lower East Side.
