It also represents the acceptance of straightforward industrial design as part of modern architecture, and its prominent commercial location sets it apart from most contemporary examples, which were in isolated industrial areas.","narrative":"Harvard Square's subway kiosk sits on a traffic island where Massachusetts Avenue, Brattle Street and Boylston Street meet in Cambridge. Built in 1928 and attributed only to an anonymous Boston elevated railway engineer, it draws on industrial design. A broad copper-clad roof of cross-axial tunnel vaults dominates the building, with deep eaves showing wooden soffits and shallow rafters. Two pavilions enclose the stairwells to the subway. Their corner posts alternate limestone blocks and brick, with steel factory sash set above low brick walls, and the base is polished granite. Curvilinear iron detail at the entrance and the roof profile are the only decoration. The kiosk was listed because it works as a symbol and focal point of Harvard Square, where a courthouse stood from 1708 to 1758 and a markethouse later occupied the site. It also shows industrial design accepted as legitimate modern architecture, placed in a busy commercial area rather than on an industrial fringe.","period_of_significance":"1928","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Marked as publicly owned, occupied and in use for transportation; condition checked as good.
