Well, I've done it now. With this addition, I really will have to tackle natural/cultural heritage issues on my list. (I have been toying with heresy after reading a stunning article by Val Plumwood about the autonomy of the non-human world).
I also need to sit back and think more about why each place/object has made it onto the list. Ideally, I should write some statements of significance, and formally assess them against my draft criteria. This would be fascinating, I'm sure! but too time consuming at the moment with teaching only a week away and overdue papers to work on. Perhaps something I could ask a clever graduate student to help me with.
