Two significant items of jewellery from Northumbria in this period have survived. The Ripon Jewel, discovered in the precincts of Ripon Cathedral in 1977, is difficult to date but its grandeur and the location of the find have suggested a link with Bishop Wilfrid, whose rich furnishings of the church at Ripon are on record. Bishop Cuthbert's pectoral cross was buried with him during Aldfrith's reign, either at his death in 687 or his reburial in 698 and is now at Durham Cathedral. There are few surviving architectural or monumental remains from the period. The Bewcastle Cross, the Ruthwell Cross and the Hexham Cross are probably to be dated to one or two generations after Aldfrith's time. Escomb Church is the best preserved Northumbrian church of the period, dated to the late 7th century. The ruined chapel at Heysham, overlooking Morecambe Bay, may be somewhat later in date.
