 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 . <unk> Church is the best preserved Northumbrian church of the period , dated to the late 7th century . The ruined chapel at <unk> , overlooking Morecambe Bay , may be somewhat later in date .
