On the evening of Sunday, September 11, at 7 p.m., the tenth anniversary of 9/11 will be observed in a special way when the DaPonte Spring Quartet gathers to perform in the 1772 Old Walpole Meeting House in South Bristol, where creation of the new nation was debated over four centuries ago.

Tickets, $25, are on sale now for the 15th annual always-a-sellout DaPonte Candlelight Concert benefiting the all-original site. Funds raised this year will go towards painting the hand-shaved 1772 exterior shingles of the oldest continuously used church/meetinghouse in Maine still on its original foundation.

From a raised platform in the center aisle of the beautiful, intimate building, the quartet will introduce and play a particularly poignant program, designed to please and send people out into the night in a contemplative state. The quartet has chosen Beethoven’s Opus 132, “a healing piece,” Beethoven’s Opus 135, and Barber’s Opus 11, “one of the most beautiful pieces in the repertoire . . . also one of the most profound, both powerful and introspective,” according to DaPonte violinist Dino Liva.

Open seating is in the original box pews downstairs and around all three sides of the soaring balcony in the historic site, which has “the best acoustics of any place we play,” according to Liva.

An eigth-generation direct descendant of Henry Hunter (who helped create the Meeting House), Deacon Mary Hunter Bowers and Hunter family trustees will greet and seat guests, along with treasurer Fred Bowers and the concert committee members, Deb and Warren Storch, Betsy Kunkle, Larry Reed, Tim Dinsmore, Ken Smith and Sally Beaudette.

On the National Register of Historic Places, Old Walpole Meeting House is owned now by the Town of South Bristol. It is on Route 129, 3.5 miles south of Damariscotta.

Concert tickets are available at Maine Coast Book Shop in Damariscotta, the Walpole Barn on Route 129 in Walpole, and in Boothbay at Framers Gallery in Meadow Mall.

Tax-deductible contributions towards painting the Meeting House are welcome and should be sent to Old Walpole Meeting House, P.O. Box 47, Walpole ME 04573.
