Eyes Wide Open

For many people a visit to the cathedral starts them asking questions about objects in the outside world too.  As people exit the cathedral and walk through the close to the town they might be asking:

What is that room above the cloisters?
Why has the front of that statue fallen off?
Is the spire really at an angle?
What is all that metalwork round the tower?
What are those narrow windows for?
Why are there walls round the close?
Why is there a monument to Protestant Martyrs?
Why is that called the Belfry Tearooms
Why are there so many almshouses?
Where is the meridian mark?
