The story

How Port Washington came to be

From Wikipedia’s history of Port Washington.

Read it all →

What is now Port Washington was originally inhabited by the Matinecock Native Americans. European colonists – namely, Dutchmen and Englishmen – settled in the area in 1644, after they purchased land from the Matinecocks. Many of these settlers in modern-day Port Washington and across Cow Neck established farms or large colonial estates. Some of these early settlers belonged to prominent, early Long Island families – including members of the Hewlett, Sands, and Willets families, among others.
