This room is one of my favourites at the Tower of London. From around 1100, any king living in the White Tower used this room as his private chapel. You would have had to be very close to the king if you wanted to come in here.  Some big names used this room. It was actually built for William the Conqueror but he died before it was finished. So his son William II used it. Henry III added stained glass windows around 1240. Henry VIII spent time here and Charles I used it as a State records office.  The room has a really calming atmosphere, especially in summertime, when the sun shines through the back window and throws fragments of coloured light onto the floor.
