Emmanuel College in Cambridge is on St. Andrew’s street. We were led there on a tour by Professor Nicholas James. He explained the typical layout of each college using Emmanuel as an example. As you see in this video which was taken standing in front of the Porter’s Lodge: first there is the dining room which you can see has a large bow window — this lets in more light which falls on the table where the masters eat; then directly across the green is the chapel; then there are the lodgings for students and professors; and last you see the Porter’s Lodging. The Porter allows people in and out of the College. As Professor James said, the Porter knows everyone and knows who should be allowed out — or not.
