AUBURN — The Androscoggin Historical Society will lead a tour of Danville historic sites at 10 a.m. Saturday, July 16, beginning at the intersection of Danville Corner Road and Old Danville Road and continuing a mile to Danville Junction.

The one-hour tour will feature the Andrew Giddinge house, one of the oldest in town, plus the post office, grain mills, brickyards and the railroad yards that made the town well-known 150 years or more ago.

Danville, now a quiet residential community that is part of Auburn, once was a bustling center of commerce, said tour leader Betty Young, a member of the society’s board of directors and a fifth-generation Danville native. It was the junction of two major railroads, the Maine Central and the Grand Trunk, during the time when railroads were the principal means of passenger travel and the shipment of goods.

Participants will drive between sites, Young said. There will be no charge for the tour, although donations to the society will be accepted. A map and information about the sites will be provided.
