Hamilton Mausoleum

The Mausoleum is the resting place of the Dukes of Hamilton and until recently held the record for the longest echo within any man-made structure in the world, taking 15 seconds for the sound of a slammed door to fade.
 As a student in Hamilton xxx years ago we were due to visit the Mausoleum with our music class to experience the amazing echo unfortunately the visit was cancelled now at last I'm going on the tour on Sunday. I took the photo today and hope to have inside shots on Sunday!
