Tour Gold Coast Mansions on Long Island

From the Roaring 20's until the Great Depression, Long Island's North Shore from Nassau County to Suffolk County's Huntington Township was comprised of numerous homes for the wealthy and famous. "The names of the industrialists and bankers who, benefiting from America’s second industrial revolution, sought to outdo each other with the size and ostentation of their castles are a veritable “who’s who” of the “Gilded Age.” All over the region, Astors, Guggenheims, Morgans, Vanderbilts, and other capitalists with seemingly inexhaustible resources erected homes in practically every great architectural style imaginable, often raiding the great homes of antiquity in Europe to acquire ornate decorative and structural components that soon were installed in Long Island palaces." This affluent stretch of the North Shore became known as the "Gold Coast". The name still persists today even if many of the Gold Coast mansions no longer remain. The remaining Gold Coast mansions serve varied functions from event spaces, museums, educational centers, museums and more. Take a tour of one of the incredible properties to take a trip back in time to the era of the "Great Gatsby" and all its extravagance.

Tourable Mansions

Nassau County

Chelsea Mansion at the Muttontown Preserve - East Norwich- "40–room mansion, named to the National Register of Historic Places in 1979, was built by Mr. and Mrs. Benjamin Moore in 1924 and is an outstanding example of the design ideas prevalent during the latter part of Long Island's Gold Coast Era. A blend of French, English and Chinese influences, the mansion provides a sense of mood, elegance and charm, while achieving well-proportioned, livable interior spaces. The mansion is open to private events and tours on select days." Take a tour

Coe Hall - Oyster Bay- "a 65-room Tudor Revival mansion designed by architects Walker & Gillette. It began to take its current form in 1913 when the land was purchased by William Robertson Coe, an English immigrant, and Mai Rogers Coe, heiress and daughter of Standard Oil partner Henry Huttleston Rogers. The landscape was largely the vision of the Olmsted Brothers Firm and retains its original 409 acres of greenhouses, rolling lawns, formal gardens, woodland paths, and plant collections. Made to look as if it stood for centuries, the architecture and design of Coe Hall is a showcase of artistry and craftsmanship that features a distinctly American aesthetic through whimsical interior decoration by Elsie de Wolfe, original ironwork commissions by Samuel Yellin, and murals painted by artists Robert Winthrop Chanler and Everett Shinn. Planting Fields has been included in the National Register of Historic Places since 1979." Take a tour

The Frick "Clayton" Estate - Today "Clayton" is the Nassau County Museum of Art - Roslyn- "The property originally belonged to William Cullen Bryant. "In 1862 Bryant built a Gothic Revival board guesthouse on his Upland Farm, now the Museum property.... In 1900, Lloyd Stephens Bryce purchased Bryant’s Upland Farm and commissioned the architect and tastemaker Ogden Codman to design a neo-Georgian mansion on an elevated site overlooking Hempstead Harbor, now Nassau County Museum of Art.... In 1919 Henry Clay Frick, co-founder of US Steel Corporation and world famous art collector, purchased Bryce House as a gift for his son and daughter-in-law, Childs and Frances Frick. They hired British architect Sir Charles Carrick Allom to redesign the facade as well as the interior of their new home, which they named Clayton. The grounds at Clayton developed by the Fricks were among the foremost landscapes in America." Take a tour

Guggenheim Estate - Sands Point - "The Sands Point Preserve on the original Guggenheim Estate embodies the grandeur and elegance that define the Gold Coast period of the early 20th century, when prominent American families built great mansions on large estates as summer retreats along the Long Island Sound.  The Sands Point peninsula was the famed “East Egg” in F. Scott Fitzgerald’s “The Great Gatsby.”" The Guggenheim Estate/Sands Point Preserve is composed of four mansions- Hempstead House, Castle Gould, Falaise, Mille Fleur. Take a tour

Eagle's Neck - Centerport- "Eagle’s Nest is the summer home of William K. Vanderbilt II, the great-grandson of Cornelius Vanderbilt.

Over the next 30 years, the house grew into the sprawling 24 room Spanish-Revival mansion that is seen today. Eagle’s Nest was designed by famed architects Warren and Wetmore, who took inspiration from the architecture of Spain and Northern Africa, and adorned with ironwork made by master craftsman Samuel Yellin. Unique among many mansions, Eagle’s Nest was not only built with living space for Mr. Vanderbilt and his family, but also museum space where Vanderbilt could showcase the thousands of natural history and cultural specimens he had collected from his travels."

Oheka Castle- Huntington - "financier and philanthropist Otto Hermann Kahn built OHEKA CASTLE in the middle of a 443-acre plot on the highest point on Long Island in Cold Spring Harbor for an estimated cost of $11 million ($158 million in today’s currency). At the time of its construction, the French-style chateau was—and still is today—the second-largest private residence ever built in America. After Otto Kahn died in 1934, the estate changed hands several times, serving as a retreat for New York sanitation workers and a government training school for Merchant Marine radio operators. In 1948, the Eastern Military Academy bought OHEKA, bulldozed the gardens, subdivided the rooms, and painted over the walls. After the school went bankrupt 40 years later, OHEKA stood abandoned, except by vandals who set numerous fires over five years. In 1984, developer Gary Melius purchased OHEKA and the remaining 22 acres that surrounded the estate and began the painstaking challenge of restoring the Castle to its original grandeur."
