Bonnie ~~ Ely Cathedral is easily visited from Cambridge: only about 12 miles between the two cities. It is a very beautiful cathedral, with its unique 'Lantern-Tower and Octagon' feature. Look out for its appearance on a clear day, dominating the landscape all the way on the A10 road after the bend between Waterbeach and Stretham, when the Tower + the Lantern as it seems to sail over the flat fields well justify its nickname The Ship Of The Fens. It also has an interesting tombstone in the South Porch with an astonishing poem on it called The Spiritual Railway, well worth any folkie's time:

Make sure to find the right doorway into the small porch/courtyard where it is. Any of the vergers or guides would help. There is also an excellent Stained Glass Museum there.

Long time since I punted down the Granta from Cambridge to Grantchester ~~ but I am sure they will still be serving honey for tea at the Orchard! If too old or tired to punt, an easy drive.
