A movable, usually solid, barrier

Doors. Flicking through the pages of the Internet over the weekend, I saw an article, or series of pictures about a Portuguese photographer who has done / is doing a feature on doors. I found it fascinating, thinking about what goes on behind them etc and it got me to thinking about my own doors.... Apart from when I lived at home as a child I've had just three houses and six doors if you count front and back. And I've only ever liked two of them. This is not one of the two, but it is the current front door.
I shall dig up pictures of my two favourite doors, both of which I miss quite a lot now I come to think about it.
