A Bunch O' Brass #3

The last time I saw a doorway this ornate I was sightseeing in a cathedral. I wonder how they keep all that brass shining without a crew of hundreds of rag-weilding gnomes polishing every inch of it constantly throughout the day? Either it's not brass, which I refuse to believe, or they sealed it beneath a protective transparent overcoat after first polishing it to a high gloss. The effect is dazzling.

I didn't notice until I posted this photo that the clock was broken, or possibly it's running eight hours slow.
