At the top of the Barcelona Cathedral, round windows reminiscent of hobbit dwelling windows!

The Round Church in Cambridge is probably one of the oldest surviving buildings in the city.
Dating from 1130AD, this is (according to the website) one of only 4 circular churches in England. It is now maintained by Christian Heritage. Not the easiest building to take a picture of, sitting as this is on a busy crossroad in the city. A lovely little church, well worth the visit for sheer character and history.
