Ely Cathedral

Ely Cathedral's unique octagonal lantern tower, built after the Norman tower collapsed in 1322, is one of the most daring and beautiful feats of medieval English engineering: eight stone ribs soar up to an octagonal wooden lantern that floods the crossing with natural light, creating an interior experience of divine illumination that the cathedral's own theologian-builders understood through Revelation 21:23 ('the city does not need the sun or the moon to shine on it, for the glory of God gives it light'). The Prioress Etheldreda's original foundation on the Isle of Ely (echoing Psalm 46:4 'there is a river whose streams make glad the city of God') gave the cathedral its name (Eel-land), and its Lady Chapel (1349) is the largest medieval Lady Chapel in England. The octagonal form consciously echoes the eight-sided baptistery tradition of divine rebirth.
