Hobson Street wall
The somewhat grimy yellow bricks that seperate Christ's College from Hobson Street in Cambridge. Although right in the middle of town, Hobson Street is often rightly overlooked, containing as it does the fire exits of Marks & Specncer's and Waterstone's (yes, with an apostrophe) and a closed down, boarded up bingo hall. And the wall of Christ's. It is presumably named after Thomas Hobson, the 16th/17th century livery stable owner who is the source of the phrase Hobson's choice.
