Willowmere

Willowmere, also known as Pearsall House, is a historic home located at Roslyn Harbor in Nassau County, New York. It was originally constructed about 1750 as a $2 1/2$-story, gambrel-roofed dwelling with a five-bay front facade. It was expanded in 1893. It was the property of Admiral Aaron Ward (1851-1918), a rose lover. The portico was added in 1926, when the house was renovated to the Colonial Revival style.

It was added to the National Register of Historic Places in 1999.
