Plaque

Referring to the plaques, as viewed by the people in our photo who are reading them the right way up:
At the left: George V Silver Jubilee;
Middle column, from the top: Queen Elizabeth II Diamond; Queen Elizabeth II Golden; William Wallace; Queen Elizabeth II Silver;
At the right: Simon de Montfort;

and on a lower step, but not visible in our photo: Charles I;

and on the next landing down:
an empty space left by a plaque that has been removed (interesting but we have no information); and Mandela.

This south end of the hall has been through a number of changes. We found images at Living Heritage and Alamy and Explore Parliament.
