York Minster

Or, in plainer English, York Cathedral.
One of the great cathedrals of Europe; a fabulous medaeval Gothic building. Even if you are not particularly interested in architecture or religion, don’t miss this if you are in the area. You’ll be impressed by this soaring creation of intricately carved stone. It shows what our ancestors thought was worth spending effort and money on – while the peasants lived in fetid huts, God and his servants got to use a building like this. And yes it has its own website: York Minster.
