The picturesque area known as Port Washington encompasses several villages near Manhasset Bay that are unified by a zip code and a first-rate school district.  Decades of economic change and migrations have resulted in a diverse and attractive seaside community that continues to charm newcomers with its natural beauty, country appeal, continuing prosperity, and colorful cultural mix.  Wonderful shops and antique dealers combine with restaurant row to complement attractive neighborhoods of lovely homes.  Homes in the Port Washington area range from historic mansions to waterfront manors with beach, mooring, and water rights.  Recreational amenities are superb and include nearby beaches, yachting centers, golf clubs, swimming pools, and lush parks.  The architectural treasure of the restored Jeanne Rimsky Theater offers comfort and high technology in a vintage atmosphere.  Port Washington is a study in contrasts, from the antiques row on Main Street to modern suburbia, from Gold Coast opulence to tree-shaded neighborhoods.
