The bells are a tradition in this charming American town. If you think they'll bother you, come stay in a B & B for the weekend. You may find you don't even hear them after the first day. Their caroling causes most people to stop in their tracks and smile.
They don't ring all night long, by the way. But even so, their sound is soothing and rather assuring somehow. Sort of a "God's in His Heaven, all's right with the world" type of feeling.
How far away they can be heard depends on the weather (further in calm, clear air) and the sensitivity of one's hearing.
