Trip in lift or up staircase will give public access to treasures in 13th-century attic space being transformed into a museum
When the floorboards came up in the attic of Westminster Abbey, centuries of rubbish and thousands of pieces of fragile treasure were revealed: the sackloads of dust were sieved to make sure nothing was missed. The finds included a wooden Dutch clog, a clay pipe and 31,000 fragments of stained glass, some dating back to the 13th-century construction of the present church.
Some of the fragments came from windows blown out in the Blitz, some from the glass-smashing fury of the Reformation iconoclasts. All have been saved and carefully cleaned, and thousands are being reassembled into windows for a glass bridge linking a new tower, which will bring the general public for the first time into a hidden world.
