I'm one of those weird people that isn't religious at all but really loves churchs and chapels. I find them beautiful, peaceful spaces and generally find any space in which people spend time believing in whatever the believe in quite a beautiful thing.
The chapel at the Royal Naval College is a beautiful space. Obvious seafaring related connotations aside, its a simple quiet space that I enjoyed taking a few moments respite from the cold in when I visited last weekend. The monument to the men of Erebus and Terror upon entry hold obvious relevance, those great ships and their men remembered in some epic stone sculpture is happening right there you guys.
