 The largest bell weighs a ton and used to vibrate the foundations.They are the only 'ringable' peal of church bells on the whole continent of Asia (there is another peal of bells at the Church of the Holy Name in Pune, India, however these are considered 'unringable' because the tower is cracked, and could not withstand the stresses associated with change ringing).Another important possession of the cathedral is a huge organ, which is currently not in use.
