York Minster's glass returns to window

30 July 2014 Last updated at 23:26 BST

Glaziers have begun to return the renovated stained glass to York Minster's Great East Window.

It is the largest Medieval stained glass window in the world and is more than 600 years old.

The window is the centre of a £20m restoration project that has seen the glass removed, cleaned and repaired.

Now skilled craftsmen have started the job of putting the glass back in the window alongside a new protective layer.
