St. John's Colleges exist in Oxford and Cambridge in the U.K. and in the University of Sydney in Australia.
It was said that the St. John's colleges in Oxford and Cambridge were so rich that you could walk from the St. John's College in Oxford to the St. John's college in Cambridge always walking on land owned by either college.
Sadly, the St. John's College in Sydney isn't quite as affluent (I stayed there for four years).
