The Roof Of Great Hall

The magnificant roof of the Great Hall is a rather complicated form of arched-brace construction, having collar beams at two levels and two lines of purlins. Many of its members are moulded. In 1748, Archbishop Herring was so concerned about the thrust exerted by a roof of such a large span, that he had three tie beams inserted to prevent the north and south walls from spreading. One of these beams bears his initials and date.
