I second the motion for Durgin Park Restaurant in the Quincy Market shopping complex next to Faneuil Hall. Used to walk there for lunch often. Used to be two lines, the tourist line (long and slow) and the lounge line, where if you got a libation first, you got into the restaurant quicker. Haven’t been there in a long time, tho. The Museum of Science is in Boston on the Charles River Dam that separates Boston from Cambridge. It now has the fantastic Zakim Bridge in front of/over it. That’s the widest cable-stayed bridge in the world and part of the notorious Big Pig, er Dig, the $14 billion tunnel/bridge complex under the downtown that took 12 years to build. That’s worth a trip (they have tours) if you’re into that. It may still be leaking. If you want to get high, visit the observation decks at either the 52-story Pru Tower (I used to work on the 48th floor), or the 60-story mirror-clad John Hancock tower in Copley Square. The latter is beside a 150 (?)-year-old church, with a very contrasting architecture. It also was the one whose windows kept shattering and falling to the street until they boarded them up and then installed a mass damper in the upper stories to absorb the undulations. The New England Aquarium, on the harborfront, is impressive, 'tho I’ve never been there. In the Italian North End you can visit Paul Rever’s House, Bunker Hill and its monument, and the US Frigate Constitution (Old Ironsides). Out Huntington Avenue, are the Museum of Fine Art and the Gardner Museums (I went thru college across the street from the MFA).
Walk the cobblestone lanes of Beacon Hill (I used to live on the top/10th floor on its summit and walked to work in 7 minutes (rent was $125/month, like I said, a long time ago)). Visit the middle-of-town Boston Common and Public Gardens, and the Champs-Elyses-style Commonwealth Avenue, radiating from the Gardens to Fenway Park )home of the SOX) at Kenmore Square. BTW, starting at the Gardens, the grid section cross streets are named alphabetically between those points-Arlington, Berkely, Clarendon, Dartmouth, Exeter, Fairfield, Gloucester and then the breaker Mass. Ave. On the Common, across from Charles Bulfinch’s gold-domed State House, is the impressive memorial to Robert Gould Shaw’s Black Troops glorified in the movie, “Glory”. Try the John F. Kennedy Memorial Library at what used to be called Columbia Point. And while landing or taking off from Logan Airport, check out the three-decker close-in urbs, East Boston (under Logan’s aircraft approaches), South Boston, and the 1860’s Back Bay and the gentrified South End. Most of the city is on filled land (read “Boston: A Topographical History”, by Walter Muir Whitehill). The airport is on filled land in the middle of Boston Harbor, 1 mile from Downtown! The Ted Williams, Sumner, and Callahan Tunnels run between the historic North Shore, Logan and Downtown. Take cabs if you want to get stuck in traffic. Do not drive. Better yet, pick up a T System map and ride the subway or walk.
The Freedom Trail is very historic and patriotic-the Old State House, whence was read the Declaration of Independece, overlooking the site of the Boston Massacre (I overlooked its roof from my 21st floor office at One Boston Place, the big black building with the box on top) next to Maison Robert, (if still there), a fine French restaruant in the OLD City Hall. You can’t miss the “new” City hall, with its overhanging crenellated eaves that project out further as you go up, surrounded be a sea of brick, next to the oldest buildings in the city. Across Tremont Street from the Parker House is the Granary Burial Ground where lie buried John Hancock, Paul Revere, Samuel Adams and Ben Franklin’s parents.
I haven’t spent any time in the city for many years but studied and worked there for as many. Well, probably TMI already, but I think you can still get scrod at the Parker House (Bostonian “in” joke).
