The Gothic cathedral of the Bishop of Bath and Wells (aka "the Bath Abbey") was founded in 1499 after Bishop Oliver King experienced a vivid dream of angels climbing up and down ladders to and from heaven.
He also heard a voice declaring: "The crown should plant an olive tree and the king restore the church." Interpreted as a sign to rebuild the church (the site had been used by Christians as a place of worship since AD 757), the dream was intricately immortalized in stone on the building's west side.
