FRANKFORT — The Frankfort Hill Historical Society District No. 10 Schoolhouse will be open for a series of guest lectures.

All of the lectures are scheduled to begin at 6:30 p.m. at the school, located on Frankfort Hill near the intersection of Albany and Higby roads next to the Frankfort Hill Volunteer Fire Co.

The lectures scheduled are:

• Monday, June 20 — Becky Sokol, Local Civil War veterans;

• Monday, July 11 — Jim Greiner, “Wicked Herkimer County;” and

The District No. 10 Schoolhouse is on the National Register of Historic Places and chartered by the New York State Education Board of Regents, the society said in an announcement. The group’s purpose is to provide an educational insight into one-room schools in the area and to preserve the District No. 10’s one-room school house, its artifacts and records, and the documents and artifacts of the surrounding region.

The society opens the schoolhouse for special events, lectures on local history, and visits by local school children.
