The Cathedral Church of the Holy Trinity, founded in 1075, when the seat of the bishop was moved from Selsey to Chichester, is consecrated in 1108 under Bishop Ralph de Luffa.
The plan of Chichester Cathedral is in the shape of a cross, with an aisled nave and choir, crossed by a transept.
Much of the original Norman construction remains in the nave, transept, crossing and adjacent bays of the choir.
The elevation rises in the usual three stages of arcade, gallery and clerestory.
It is similar to remaining Norman work at Winchester, where the arcade is proportionally low, and rests on solid piers rather than columns.
In the gallery above, each wide space is divided into two by a colonnettes in a manner typical of Romanesque architecture.
