Visitors will be able to enjoy a new exhibition while the site is closed, however.
GREENWICH, CT — The Bush-Holley House, a National Historic Landmark and centerpiece of the Greenwich Historical Society, will close to the public beginning Oct. 1 for environmental upgrades designed to preserve its collections and improve the visitor experience, according to an announcement.
The historic home is expected to reopen in April to coincide with the 250th anniversary of the Declaration of Independence and related programming organized by the America 250 Greenwich Commission.
"We are deeply grateful for the state and town funding that will enable us to achieve our long-term preservation and sustainability goals," said Greenwich Historical Society Executive Director and CEO Carol Cadou, in a news release. "These upgrades will ensure continued stewardship of our historic collections for the thousands of visitors and school children who come to our campus each year for a greater appreciation of our shared past."
The project is supported by a 2023 Good to Great Grant from the Connecticut Department of Economic and Community Development in partnership with Connecticut Humanities, a Community Development Block Grant Program, and private donors.
Built in 1728, the Bush-Holley House has been both a Revolutionary War-era landmark and the home of the Cos Cob art colony, the first Impressionist art colony in Connecticut.
While the house is closed, visitors will be able to see highlights of its Impressionist collection in a new exhibition, The Holley Boarding House: Inspiring American Impressionism, running Oct. 8 through March 8, 2026, in the Historical Society’s Museum Gallery.
The exhibit focuses on the Holley women who ran the boarding house from 1891 to 1920 and welcomed artists such as Childe Hassam, John Henry Twachtman, and J. Alden Weir.
A companion exhibition in the Permanent Collections Gallery will feature works donated by scholar and collector Susan Larkin, showcasing the range of artists who contributed to the art colony’s experimental spirit.
Guided tours of both exhibitions will be offered Wednesdays, Thursdays, and Sundays at 12, 1:30, and 3 p.m., beginning Oct. 8.
On Fridays and Saturdays, behind-the-scenes archive tours will display rarely seen maps, ephemera, and other primary sources. Archive tours will also run at 12, 1:30, and 3 p.m.
From Oct. 1 through Oct. 5, the entire Historical Society campus will be open free of charge, with access to the gardens, Permanent Collections Gallery, and Museum Store.
Advance reservations for tours are encouraged and can be made at greenwichhistory.org/book-a-tour.
