Below the copper tower, a brick room holds the organ-like device that the musician uses to ring the bells. We got quite a kick out of her 20-minute concert, performed by hammering on the levers with her fists and stamping on the pedals with her feet. She studied seven years to learn to play the instrument and gives a live performance every Sunday during summers. (The bells ring every hour, using tunes she programmed in previously — I guess there’s an automated setting?)
