The Delamater-Bevin Mansion, also known as The Bevin House, is a historic 22-room Victorian mansion on the north shore of Long Island within the Incorporated Village of Asharoken, New York.

The home was built by Cornelius Henry DeLamater in 1862 in the French Second Empire architectural style and was initially known as Vermland.

DeLamater named his summer estate "Vermland" after the Swedish province where Ericsson was born, as the two men were best of friends and inseparable.

[3] During World War II, the exiled French writer and pioneering aviator Antoine de Saint-Exupéry rented The Bevin House, where he wrote much of the well-known novel The Little Prince in late 1942.

The Delamater-Bevin Mansion was added to the National Register of Historic Places in 1985.
