Back in 2004, our first apartment in Beirut had a metal outer door to guard or block the actual apartment door for extra security. I believe we never actually closed (much less locked) that 'extra' security door the whole time we lived there, but anyway . . . these metal outer-doors are common throughout the city, and though you'll find them everywhere you'll notice that there are very few alike. There must be some creative metal-workers in town.
I liked the symmetry, right angles, and repetition in this door. And I'm feeling a bit gray as I write this, so it fits.
