A tiny hamlet on the Hudson River, Garrison has deep roots in our nation's history. Author George Carroll Whipple III has compiled beautiful images of this tiny hamlet and made efforts toward restoring to its former grandeur the iconic 1881 Castle Rock, the estate of William Henry Osborn, a visibly prominent and renowned landmark for all who reside in or visit Garrison. Many wealthy New Yorkers such as William Henry Osborn, Edwards Pierrepont, and Hamilton Fish built their impressive summer estates here and many of those manors still stand today.
