There is a group here in Brussels, the Bronte group, that apparently do literary walks around in Brussels. I was going to mention it here. This is the excellent post for it. Also, next year there is some sort of anniversary I believe. I can find the link and post it here!
It's the direct link to the events page and there's the Annual Brontê Weekend. They have some professor coming over and on the sunday (april 2010) there's a guided walk in Brussels. But maybe we can propose to make an evening with tea and cake or some dance on the saturday. At least ask!
