Union's Kelly Adirondack Center will be open for public tours on three Wednesdays in August.
Visitors can tour the center at 897 St. David's Lane in neighboring Niskayuna from 1 to 4 p.m. on August 7, 21 or 28.
The Kelly Adirondack Center includes a historic 2,400 square-foot Dutch replica home built by noted Adirondack conservationist Paul Schaefer in 1934 that was used for offices and meetings.
A 3,900 square-foot addition contained additional offices, conference rooms and the Adirondack Research Library, which boasts the largest collection of material outside of the Adirondack Park, including rare books, maps, photographs, documents and the personal papers of some of the region's foremost conservationists.
Union acquired the center in 2011 from a private conservation group.
