Delamater–Bevin Mansion

The Delamater-Bevin Mansion is a Victorian house with 22 rooms located on the north shore of Long Island, overlooking Northport Bay from Duck Island Harbor. Built in the French Second Empire style, the residence sits on approximately 1 acre and earned recognition on the National Register of Historic Places in 1985.

Cornelius Henry DeLamater, owner of DeLamater Iron Works, built the mansion in 1867 and named it Vermland to honor his Swedish friend John Ericsson. His iron foundry became notable for manufacturing critical components used in the Civil War ironclad USS Monitor.

The residence gained literary significance when French writer Antoine de Saint-Exupéry worked on The Little Prince during his time here in World War II. Today visitors can see a place connected to one of the world's most beloved books.

The house sits on elevated ground with water views and offers insight into 19th-century architectural design and coastal living on Long Island. Visitors should allow time to explore both the building and its grounds to fully appreciate the site.

Few visitors realize the property was originally named Vermland, reflecting a close friendship between its owner and Swedish engineer John Ericsson. This personal connection to maritime engineering runs through the property's location and the region's shipbuilding heritage.
