About this room

Built in 1939 our stunning Grade II Assembly Hall was designed by world-renowned architect Sir Herbert Baker. Natural light streams through the 15 arched windows onto the gallery level, but can be darkened if required.

The polished English oak paneling and emblems sit beneath the room’s architectural focal point - a striking 30-foot glass dome.
