Hi-Tech Leeds Minster with buried level i was told does not exist.

Sorry i call this place Hull minster when of course it is Leeds Minster. This is a strange one as they would not let me video inside so i have had to add the stills of inside at the end ALSO i asked twice if the church had a lower level of any sort even an old boiler room or disused store rooms anything at all below the level we were standing on and i was told a definite No. I show both on the video and stills at the end of the lower level i was told does not exist. The still pictures of the lower level are of better quality than the video so its worth watching till the end. ... https://www.youtube.com/watch?v=09cislmczEU
