In plan the northern wing repeats the southern: three aisles of four arches on five columns.
But its eastern wall holds a small rectangular room, thought to have been a minor apse, which was later turned into a funerary chamber. Inside it are three massive tombs with their covers, of the tenth century.
Who they were for is not recorded. The likeliest reading is senior monks, or benefactors who had done well by the church and were buried where every prayer said in the building would pass over them. That is a particular kind of arrangement: not a graveyard outside the walls, but a place inside the liturgy.
