Heck, I'm from NZ. There are plenty of houses in the US, let alone the UK, centuries older than anything we have here.

I visited the UK two years ago and was seriously gobsmacked by the casual ancientness and layered history of everything. A random stationery shop in Bath had cutouts in the walls and floor showing the original Georgian wallpaper and such, and that was a hop skip and a jump away from the Roman baths and what looked like a medieval cathedral... and everyone was just going about their lives as if this were perfectly normal.

So. Unbelievably. Cool.
