These are photos of some ruins and a very abandoned brick factory building on Dennings Point in Beacon, NY.  The ruins that I found may be associated with the Denning family mansion, which was in ruins by the 1920s.  The Denning’s Point Brick Works was founded and operated on the property from 1881 to 1939.  Denning’s Point was also used by swimmers in the 1920s and 1930s and became known as the “Coney Island of Dutchess County.”  From 1947 to 1954 the site was operated by a manufacturer of construction panels called Durisol.  From 1954 and for 34 years thereafter, the The Noesting Pin Ticket Company operated on the site creating wire products.  In 1988 the property was purchased by New York State and became Denning’s Point State Park.  In 2006 the Beacon Institute for Rivers and Estuaries began renovation of one of the existing buildings to become the new home of the institute.
