One of Beverley Minster's many narrow spiral staircases. Until relatively recently

there was no lighting on the staircases and staff would have to use a candle for illumination.

If the candle blew out they'd be left completely in the dark.

Steve Rial, a maintenance worker and plumber at the minster, stands inside a giant treadwheel

in the minster's roof space. Steve walks inside the wooden wheel which can be used to raise

bulky items from the minster floor to the roof.

Verger John Dell indicates the height of the ceiling, which means that to change a light bulb

he has to wear abseiling gear.
