This is the last one remaining. It sits next to the modern town hall in the city centre. It has been opened up and one can visit the interior.
The inner cone has only been partially rebuilt just to show what it would have looked like. Underneath the floor the coal furnaces were stoked, the smoke being led away to a separate chimney.
At eye level around the inner cone were spy holes so that the potter could see what was occurring in the kiln and judge when best to withdraw the pots.
