Local history, contemporary art.

The Century House Historical Society is a not-for-profit educational organization dedicated to the preservation of industrial history of the Rosendale natural cement region. The Society is located at the Snyder Estate in New York’s historic Hudson Valley.


The Snyder Estate is now closed and too icy to visit, so for safety’s sake, stay out of it until it thaws in the spring!

When it’s open, the site hours are sunrise to sunset for self guided tours daily, with the museum being open Sundays from Mother’s Day through Labor Day 1PM – 4PM

Free for members, all others please leave a donation!
