Monument Square (Portland, Maine)

Monument Square (formerly Market Square or Haymarket Square) is a town square in downtown Portland, Maine, about halfway between the East Bayside and Old Port neighborhoods. One Monument Square and One City Center are among the buildings on the square itself, while the Time and Temperature Building, Fidelity Trust Building and the main branch of the Portland Public Library are on Congress Street, across from the square.

Until the 20th century, Middle Street originated from Market Square. It ran east through where The Maine Lobsterman statue is today, before continuing its current route from its intersection with Temple, Spring and Union Streets. The original stretch, which formerly met Federal Street in the square, is now paved with bricks and is no longer Middle Street.
