A Church Gate in Cambridge

When I first saw this medium format colour slide, I thought it was a picture of the church gate in Canterbury but on closer inspection it is subtly different so I assume this is a similar building in another city in the UK. The Ford Anglia which is just caught in the bottom left-hand corner dates the photo to probably the 1960s.

Update: This has been identified as the Gatehouse of Christ's College Cambridge by a viewer from Twitter - Thanks.
