Oxford -last day in England

Our wonderful holiday came to an end today. We spent the day exploring Oxford, riding on the open bus (it was freezing cold, but not raining), and walked a lot. We walked from our B&B to town, and passed lots of interesting buildings and houses. The guide on the bus told us later that real estate is very pricey in Oxford, and that a lot of the big houses have been converted into lodging for students. She said if one sees lots of bicycles in front of the house, students live there, but if there are some posh cars, it is the owners. I see on the picture there is a guy walking past this building, he looks a lot like Prince Philip to me!
