AUGUSTA — The Kennebec Historical Society’s annual meeting and program will begin at 1 p.m. Sunday, Jan. 19, at Viles Arboretum, 153 Hospital St. (across from Riverview Hospital). The meeting will start with a potluck lunch, a business meeting will follow and then the program.

The architecture of New England houses was shaped not only by its architects and patrons, but by available materials and prevailing architectural style. The Jackson House in Portsmouth, N.H., was built in the 17th century; the Gropius House is a mid-20th century modern home in Lincoln, Mass. These and other houses that are part of the museum collection of Historic New England will be the topic of Joanna McKnight’s presentation illustrating her exploration of the vast changes in architectural environment over a four-century span.

Manager of Historic New England’s Stewardship Easement Program’s easement throughout Maine, northern Massachusetts and New Hampshire, McKnight, a recent graduate of the master of architectural history program at the University of Virginia, also holds a degree from North Carolina State University.
