The cemetery and memorial park, operated by the not-for-profit Nassau Cemetery Association, was founded by the Lewis family in April of 1900 and has been taking care of Long Island families for more than 100 years. Spread across just under 40 acres, the grounds feature more than 25 sections accommodating inground burial, mausoleum crypts, monumental work, and cremation, along with a selection of mausoleum spaces, upright headstones, and flat bronze markers. Several generations of Long Island's founding families, including Bayles, Lewis, Hyde, Borden, Baymen, and Walters, rest on the property. The Memorial Park area was added in the late 1930s, modeled on California cemeteries that removed upright headstones in favor of a park-like landscape, and the grounds remain known for their green rolling hills, meandering pathways, and shade provided by oak and cherry blossom trees. The office sits on the northern edge of the property, where staff are available Monday through Friday from 8:30am to 4:30pm, on Saturday from 9am to noon, and closed Sundays, with additional closures on listed holidays. Power washing and sandblasting services help families maintain headstones and mausoleums. The cemetery holds a rating of 4.30 based on 28 reviews. Nassau Knolls Cemetery is located at 500 Port Washington Blvd in Port Washington, NY. After more than a century of service on the north shore of Long Island, the cemetery remains a fixture for Port Washington and surrounding Nassau County families seeking a peaceful, park-like setting for their loved ones.
