So agree about cathedrals. They seem to cast a mist of time over reality. Not at all Christian, much more Pagan. You feel centuries stretching away under the stones. Winchester is certainly a good one; visited a few times while on hols in New Forest. Peterborough is fascinating. Not least for its heating. No, don’t mock. Its “radiators” are, if I remember right, monstrous 10 ft across cast iron, freestanding monsters about 6ft tall and in the middle of passageways. Don’t know if they put them on any more.
Southwark cathedral also good. Sung in the place many time (Messiah, Passions etc.). Again, very ancient and even more so being right by the Thames. I’m sure the River Gods approve; reckon they like the music! (Acoustics are tricky, have to leave a second or more at end of big phrase to let the reverb soak up what you’ve just sung. In Dulce Jublio had to be sung very slow or it got lost)
