Anyone that knows of a third WHS that holds 'golden doors'?

I've got these now:
- White Monuments: Cathedral of the Nativity in Suzdal
- Florence: Duomo (Baptistry)

Golden doors or "golden gates"? There are several of the latter, in Istanbul, Kiev, Vladimir and of course Jerusalem.

You mean a real golden door or just gold gilding?
Florence Baptistry's Gate of Paradise is actually Bronze door with gold cover.

Real golden doors will be scarce I think, so a gilded cover is allright too

How about
1. Kyoto - Kinkakuji Pavillion whole buiding is covered by gold leaf including doors and also Nijo castle - many doors are also covered by gold leaf.
2. Luang Prabang, Laos - many royal temples doors and windows are gilded cover especially at Wat Xieng Thong
3. Bhaktapur, a part of Kathmandhu Valley has a famous golden gate (sun dhoka), the door is wooden I think, but the door frame is golden.

4. Mezquita in Cordoba also has golden doors
5. Istanbul's Topkapi Palace Sultan Bathroom door is gilded cover.
6. Versailles Palace has many gilded doors. (and if versailles has, many european palaces may also have -Caserta? Fontainebleau?)
