Belmont, New Hampshire - circa 1970s
Here's another mall not covered here yet. The Belknap Mall, the lone enclosed mall in the Lakes Region of New Hampshire. The above photo (which I believe dates to the '70s) was taken before a late '80s expansion, which added a Zayre store to the back end. Dead Malls has a short history page if you'd like to know more (they're apparently calling it dead).
Though I list the mall's history going to the present (for the place is still there), it appears it's currently got a lot of vacancies and/or non-retail tenants filling its floorspace, so it's not exactly a thriving, fully-functioning shopping mall right now.
