The Door - 3/20/15 - Image-a-day

I took a different route home today to avoid the Friday traffic. Along the way, I saw this mysterious door in a stone wall protecting a hidden space. This door is an eccentric detail for the neighborhood; the entire area as there's not much in the way of original architecture here. I wondered who carved the door. Was it a commission? Did the homeowner carve it him (her?) self? I will carve a door like this one day.

OK HW
