Front Door Challenge

The most important feature of any building is the door. Without a door you can't get inside. Of course you could go through the window, but who wants do climb through a window at the end of a long day?

Doors are special, yet they don't get the attention that they deserve. What's the most prettiest or most unique door that you've ever seen? What color was it? What was so special about it? Tell us about it, we'd like to know!
