But it's like that everywhere though, isn't it. My sister said it was 18 quid to get into westminster abbey the other day. (and it's 25 just to go up the shard. Though I appreciate that's not exactly a national institution just yet).
(and, ranting, once upon a time if you didn't have a job you got into places for cheap. but now you are just officially a workshy scrounger of course and shouldn't be sullying the view of decent hardworking families etc.)
But anyway. You could see it as a good opportunity for EH to make some money out of willing tourists. Which they can feed back into looking after other places. Because god knows their funding is getting cut back. and the obscurest places that we probably love best will get what little attention they receive reduced first.
