The Bells of Notre Dame

The bells of Notre Dame de Paris are getting a makeover; several existing bells, age about 150, are to be melted down and replaced by new bells that, it is thought, will be more like the bells of 1686. Read about the restoration here (if you're using Chrome, it will offer to translate the French for you) and in a NY Times article. Be sure to listen to the remarkable audio example of what the new bells are expected to sound like.
