It is true that the Lady Chapel was generally erected at the extreme east end, or one of the aisles near the choir was used for the purpose, because it was considered the most sacred part of the church next to the sanctuary. It was erected at the east end of the Abbey Churches of Westminster and S. Albans; in the Cathedral Churches of Winchester, Salisbury, Chichester, Exeter, Gloucester, Worcester, Wells, Hereford, Chester and Manchester; at Christ Church, Hants, where there is a chantry above, called S. Michael's Loft, which once served as the Chapter House of the Priory, but in modern times has been converted into a schoolroom; and also at the parish church of S. Mary Redcliffe, Bristol, where it is situated over a thoroughfare, after the example of several churches in Exeter. But the ecclesiastics and architects of the Middle Ages did not consider themselves bound, by a hard and fast rule, to set up the Lady Chapel at the east end. If an available site could be found beyond the Choir the Chapel was erected in that position, otherwise, the north aisle of the Church, or a convenient site near the Choir, was utilised for the purpose. The building has been erected on the north or south side of the Choir or Nave, and even at the west end when deemed expedient. It was erected on the _north_ side at the Cathedrals of Canterbury, Oxford, Bristol, and Peterborough; at the Abbeys of Glastonbury, Bury St. Edmunds, Walsingham, Thetford, Wymondham, Belvoir, Llanthony, Hulme, and Croyland, where there was a second Lady Chapel with a lofty screen, in the south transept.[7] It is on the _south_ side at Kilkenny and at Elgin Cathedral. It stands in a similar position over the Chapter House at Ripon Minster. Sometimes it was placed above the chancel, as in Compton Church, Surrey; Compton Martin, Somerset; and Darenth, Kent; or over the porch, as at Fordham, Cambs. At Ely Cathedral it is connected with the extremity of the north transept. At Wimborne Minster it stands in the south transept, whilst at Rochester Cathedral and at Waltham Abbey, Essex, it was erected at the west of the south transept. At Durham Cathedral an attempt was made to build a Lady Chapel at the east end, but owing, it is said, to the supernatural intervention of S. Cuthbert, whose relics were deposited in the Choir, the building was erected instead at the west end, where it stands under the name of the Galilee Chapel. The original Lady Chapel at Canterbury also stood in this unusual position, until the days of Archbishop Lanfranc, 1070-1089, when it was removed and the present building set up at the east end. The _aisles_ were also frequently used as "ye Chappell of oure Ladye," as at Haddenham, Cambs. [Footnote 7: "Gough's History of Croyland. 1783."]
