DRESDEN — The lead archeologist at the Fort Richmond dig will talk about the effort at 2 p.m. Sunday in the Court Room of the Pownalborough Court House.

Leith Smith of the Maine Historic Preservation Commission will talk about the fort, which once protected the Kennebec River frontier during the French and Indian War period. Excavation of the fort was required by state law before work could commence on areas that will be disturbed by construction of the Richmond/Dresden bridge, according to a press release from the Lincoln County Historical Association.

Smith will talk about how initial investigations determined that the site was well preserved and eligible for listing on the National Register of Historic Places.
