behind the pulpit is one of the alarmingly bent main support columns for the tower and to its left a bracing arch with additional vertical load-bearing put in, I think, by the architect James Wyatt as part of his major overhaul at end of C18th. At the same time a vault was put into the crossing at same height as nave vaults for bracing. Spoils the internal spatial character, but probably better than the estimated 8000 tons of tower and spire masonry falling on ones head.
Also an interesting sinuous plunge of the masonry at the 2nd transept
In the pulpit a clergylady making a very noble attempt to overlay the hordes of us tourists with an hourly reminder that it remains a place of worship
