Octagon

Although not the tallest of Ely's towers, the Octagon crowned by its Lantern Tower in wood, lead and glass is rightly considered the jewel in the Cathedral crown. Built in the 1320s in the wake of the collapse of the Norman tower, it is a masterpiece of medieval engineering.

I'm usually in Ely for meetings, no time for sightseeing but some day soon I shall make time to go inside the cathedral. The tower, with its' stained glass and painted ceilings is stunning.
