A mammoth window cleaning exercise is going on at the National Trust property Blickling Hall in north Norfolk.

It means removing 12 ancient stained glass panels for professional cleaning before they're put back again. Some of them date back to the 16th century and came from a German monastery.

The Trust's adviser for stained glass said the windows at Blickling were internationally important and it's vital they're preserved for future generations
