I walked through Mesopotamia today

For the first time ever I went along Mesopotamia Walk today (not such a strange name in this city of water, since it means 'middle of the river' and it's a track along a narrow island in the River Cherwell) and I emerged close to this building. It was only after I'd walked past it and turned back that I realised I've been here before, but approaching from the city side not the river side.

Extra: Narnia after the snow.
