Since we knew that we need to think about wrought iron doors, I always took pictures on our trips to Italy when I saw an interesting design of wrought iron work, no matter for doors, archways or windows.
Since we talk doors, I will post doors first. The following pictures are taken by myself or taken from the WWW, mainly via
flickr. (You need to click on the pictures for better details.)
Let's start with Italy:
Iron gates at the Colosseum in Rome - very simple but colossal
Two small iron gates at the
Castello degli Angeli in Rome. The first one is a very pretty small two wing gate.
Venice and an impressive iron door gate on the canal.

Sarzana, near La Spezia in Liguria: this is a very beautiful little medival town with lots of antique shops. These shops are protected by tall two wing iron gates that are leaned against the outside walls during the day when the shops are open. It is a very simple and elegant solution for wrought iron door gates. I also could picture these as a solution for us.
This is a little church in the middle of a forest in Calabria. When the church is 'closed', the altar is protected by this simple round but pretty two wings gate. I like the idea of having a more dense structure until mid hight.
This iron gate with simple "s" decor opens up to a garden in Seminara, Calabria. Seminara is famous for its unique ceramics.
This is an old iron door in Monteprandone, Marche via flickr (by pizzodisevo).
This door has a plane iron part at the bottom. This could protect from rain (splash water) and dirt. The decor is not special but the position at mid hight and upper end are interesting. Although, here, I would prefer arrows at the end.
Last Italian photo shows how the iron gates are fixed to the wall or stone door frame. The inside doors open to the inside and the iron gate or door opens to the outside.
