Two hundred and fifty years of history are preserved at the William Floyd Estate, which contains architectural features and artifacts from three centuries of American life. The Estate, which was donated to Fire Island National Seashore in 1965, is located on the mainland of Long Island in Mastic Beach, New York. The estate contains the ancestral house, grounds, and cemetery of the William Floyd family. William Floyd, a Revolutionary War general and a signer of the Declaration of Independence, was born in the house in 1734. Between 1718 and 1976, eight generations of Floyds managed the property and adapted it to their changing needs. The family used the house and property in different ways over the years.In colonial times, the Floyds ran a huge plantation; later, the family turned to business and politics, and the lands were used for outdoor recreational pursuits like hunting and fishing.The 25-room "Old Mastic House," the twelve outbuildings, the family cemetery and the 613 acres of forest, fields, marsh and trails all graphically illuminate the layers of history.

I visit there once a season. The history of the people that lived there, the buildings and the grounds are fascinating at any age. There are no high tech displays or 21st century distractions. Real history

Okay it is probably easier to get here then I think because we got very lost. However once you are there it is all worth it. This is not another restored Long Island Mansion. This is a perfectly preserved historic home dating from the 1700s...More

My friend and I wanted a Saturday morning adventure so we headed to the Wm. Floyd Estate on the Moriches Bay in Mastic Beach--not exactly on "the beaten trail" but well sign posted and tucked back into a neighborhood. Now its 613 acres are part...More

This is such an amazing site to go to. Not only is admission free, but so are the tours. Most people, even those in the town where the high school is named after William Floyd, do not know who William Floyd was. After stopping here...More
