Clapham-Stern House

Clapham-Stern House, also known as Wenlo and originally known as Stone House, is a historic mansion located at Roslyn Harbor in Nassau County, New York. It was originally built between 1868 and 1872 and turned into a premier estate in 1906 after being purchased by department store magnate Benjamin Stern. It is an asymmetrical $2 1/2$-story dwelling resting on a full basement. It consists of a main block with wings to the north and south, a tower, and a piazza wrapping around the south and west sides. It is constructed of rough-faced gray Greenwich granite accented by limestone. It has a moderately pitched hipped slate roof with copper cresting. After a major fire in 1960, the house was returned to a High Victorian Gothic style. Also on the property there is a contributing bathhouse dated to the 1920s.

It was listed on the National Register of Historic Places in 2005.
