The cathedral is suitably large and imposing with a super 14c painting to the left if the high altar and a sobering WW1 memorial under the massive organ; where two brothers died an battle (and there were many) they are listed together in death as in life.
The tower has been restored so the climb, while steep, is on decent steel and wood staircases. Good views from the top (though you can't get outside) and of the massive bells.
