The Washington Ringing Society, led by Ringing Master Quilla Roth, will perform a ringing of the Congress Bells in the Old Post Office Tower in commemoration of the 30th anniversary of the dedication of these bells and to commemorate the 151st anniversary of DC Emancipation Day. 

The Society will be performing a "quarter peal," a form of scientific or change ringing where the ringers are guided from permutation to permutation by following a specific algorithm. The performance should take about an hour and is a phenomenal treat.  Those wanting to listen to the performance will find the bells are generally easiest to hear on 12th Street across from the Old Post Office building, where the sound of the bells seems to bounce nicely off the Ariel Rios building.
