Natirar is an estate spanning 491 acres (1.99 km2) in Peapack-Gladstone, Far Hills and Bedminster, in Somerset County, New Jersey, United States. Its name is a reverse spelling of Raritan. The complex was built between 1910 and 1912. In 2003 it was sold by the estate of Hassan II, late King of Morocco, to Somerset County, New Jersey, and is now administered by the Somerset County Park Commission. Approximately 90 acres (360,000 m2) of the estate have been leased to develop that portion of the estate (which includes the mansion, stable/carriage barn and most of the other outbuildings) into an exclusive hotel, spa, restaurant complex.
At the end of a 1.25-mile (2.01 km) driveway within a 491-acre (1.99 km2) estate that occupies portions of three municipalities. (The main buildings and 327 acres (1.32 km2) are in the Borough of Peapack-Gladstone; 124 acres (0.50 km2) are in the Borough of Far Hills; and 40 acres (160,000 m2) are in Bedminster Township) The core buildings are south of Highland Avenue, east of Main Street/Peapack Road, north of the North Branch of the Raritan River and west of Lake Road. The main entrance, once at the Far Hills train station, is now just over the town line, nearly at the spot where Main Street (Peapack Road) crosses the North Branch of the Raritan River and New Jersey Transit's Gladstone Branch.
This was originally an estate for Kate Macy Ladd (1863–1945), heiress to a Massachusetts whaling, shipping and oil fortune, and her husband, Walter Graeme Ladd (1857–1933). After Mrs. Ladd's death, a convalescent home for women that she had started at Natirar in 1908 assumed control of the property. Under the terms of her husband's will, that home, run by an entity he had started called the Kate Macy Ladd Fund, was to be sold 50 years after his death. True to form, in 1983 the facility was disbanded, its assets distributed in equal parts to five educational institutions. The property was sold for $7.5 million to Hassan II, the King of Morocco, who visited the property infrequently due to its use as a permanent residence for his children as they attended Princeton University. After the king's death, ownership passed to his son, King Mohammed VI, who sold the property in 2003 to Somerset County, New Jersey (the county government is known as the Board of Chosen Freeholders) for $22 million.
The county leased 90 acres (360,000 m2) of the property, including all of the core buildings pictured here, to a local resident, Bob Wojtowicz. He began plans to renovate the buildings. The carriage house on the property was converted into a restaurant known as 90 Acres, and an attached garage was converted to a cooking school for public classes and events. It opened in late December 2009. Bob had partnered with Richard Branson from Virgin spa to convert the mansion to a resort location. Virgin's branding ended when Miraval Resorts became a partner with Bob Wojtowicz. The Miraval-branded resort does not currently have an opening date.
