Interesting meme--I may have to borrow it.

Fascinating list you've got, especially the Taaffe's Castle--I've been through Carbury, which is supposedly associated with my family name, but it's pretty tenuous altogether. Fortified houses are close enough to castles for government work, I think.

I think an onion bottle could count as technology, although the mortar and pestle is very cool. We've got my grandfather's adding machine, which is considerably less interesting. ;-)
