Maparium - Christian Science Center, Boston
Head on down to the Christian Science Center. The headquarters of the Christian Science religion, the centre features the original 1880s chapel, a glorious 1901 basilica, and many surrounding neoclassical buildings from the 1930s and brutalist buildings from the 1960s. In the centre is a long reflecting pool and a fountain where neighbourhood children play on hot days. Inside one of the buildings is the Mapparium, a room sorrounded by an inverted stained-glass globe (the map hasn't been updated since the 1930s, interestingly). Unfortunately, the Mapparium is closed until 2001, but you can still walk about the compolex and enjoy its striking monumentalism. The Christian Science complex is located between the Prudential Center and Symphony Hall along Huntington and Massachusetts Avenues.
In all my years living here I've never been in. Maybe I'm afraid they'll try to suck me into their Religious ways. I do want to go see the Mapparium. Maybe THIS WEEK I'll go. Nah.....
Visit the Christian Science Center, and give a look to the Mapparium... it is an amazing stained glass globe (30ft diameter) that provides an inside view of the 30's World...
