From the Bristol Cathedral website:
"Begun in 1298 this chapel forms an integral part of the design of the choir.
The Abbey would have been decorated with colours like these throughout.
The chapel was restored to what you see now in 1935.

"The badges on the reredos are the badges of the Berkeleys and the Royal Arms of England.
In the star-shaped niches are buried prominent people from the life of the Cathedral.
One such person is Bishop Paul Bush, first Bishop of Bristol."

The bust in the bottom right-hand corner
is of George Forrest Browne, 1833-1930:
48th Bishop of Bristol, 1897-1914.
