The retirement home of U.S. President Martin Van Buren, Lindenwald is in Kinderhook, as well as the famous Luykas Van Alen House, a National Historic Landmark said to be the inspiration for the Van Tassel Family in Washington Irving's book "The Legend of Sleepy Hollow", along with character Jesse Merwin. In honour of this fact, the Ichabod Crane schoolhouse was built next to the van Alen House in 1850, and is also a National Historic Landmark. The other two Landmarks are the James Vanderpoel House of History and the CCHS Museum & Library Building.
