Looks as though it could do with a change of water!
Definitely worth a visit as do all the old Churches and Cathedrals in the UK. Some fantastic examples of the Mason's Art can be seen and appreciated. Many interior as well as the exterior features are also worthy of the attention of a good photographer.
Look out for the distinguishing "marks" of the Mason on individual stones. Collecting "marks" can be as interesting as collecting train numbers! Or even more so!
