According to the Hudson Valley Ruins website, this former mansion in Rhinebeck, NY, the mansion was “built in 1853 for Elizabeth Schermerhorn Jones, a relative by marriage to the wealthy Astor Family… A later owner was Andrew Finck, New York City beer baron and a cooper by trade, and associate of brewer Jacob Rupert, of nearby Linwood. Wyndclyffe, then known as Linden Hall or Finck Castle, supposedly had an underground tap line from the mansion to the tennis courts.  The house was a private residence until 1936, and was finally abandoned for good sometime after 1950. Wyndclyffe remained remarkably [sic] intact through the 1980s, but decay worsened as abandonment neared the end of a half-century.”

Strawbery Hill is located on Ackert Hook Road in Rhinebeck, NY.  It is also known as the Henry Beekman house.  The house is on the National Register of Historic Places as site #90NR00355.  Based on information in a building inventory form found on the Cultural Resource Inventory System, the site is a farmstead consisting of an 18th century German stone farmhouse, a large Dutch-type barn complex, a well/wellhouse, privy, and two sheds.  Local tradition states the property was developed by Henry Beekman in 1762, but he may not have ever lived in the house.
