American Scenic and Historic Preservation Society operation Establishment of museum The ASHPS bought the Grange in November 1924 The ASHPS planned to convert the house into a museum, and it appointed a committee of several people, including two of Hamilton's descendants, to collect memorabilia for the museum. The society wanted to raise money for a renovation but still did not have sufficient funds by 1928; it hoped to raise $125,000. The ASHPS launched a fundraising campaign in early 1929 and renovated the roof the same year. The balustrades were also removed to allow the repainting of the three other facades, which was never completed due to a lack of money. Furniture and decorative objects associated with the Hamilton family were displayed there.
1930s to early 1960s Initially, the house was open to the public every day and did not charge admission fees. With the ASHPS's permission, the DAR redecorated one of the house's living rooms. A statue of Hamilton by
William Ordway Partridge was relocated from the Hamilton Club of Brooklyn after the club closed in 1936, and it was dedicated outside the Grange that October. By the early 1940s, numerous people were donating Colonial memorabilia to the museum, regardless of whether the objects were related to Hamilton. By then, the house was dilapidated; some of the upstairs rooms did not have any furnishings, and the facade needed to be repainted. As early as 1950, the ASHPS was asking New York City park commissioner
Robert Moses to relocate the Grange to
Claremont Park, where the Claremont Inn was being razed. At the time, the group's members felt that the Grange had degraded to a "shabby" condition. The city government asked the state legislature in 1955 to move the house to the
City College of New York (CCNY)'s campus, as that site was close to buses and the
subway. The New York State Assembly passed a bill that March to permit the house's relocation to the CCNY campus, and governor
W. Averell Harriman approved the bill the next month. The society planned to ask local banks for $400,000 because Hamilton had helped establish the modern U.S. banking system. The Grange had still not been relocated by early 1958, and the ASHPS was raising $375,000 to move the house to the CCNY campus. Largely white philanthropists also wished to relocate the house southward, away from the majority-black Hamilton Heights neighborhood, and there were also proposals to move the house to
Riverside Park or
the Cloisters. Ultimately, no action was taken on any of the relocation proposals.
National Park Service operation Takeover and preservation In May 1960, U.S. Senator
Jacob Javits introduced a bill in Congress to designate Hamilton Grange as a
national memorial, and the Grange was designated a
National Historic Landmark that December. The
United States Department of the Interior approved the creation of the Hamilton Grange National Memorial on the condition that the city donate land within the CCNY campus for the house's relocation.
Congress authorized the national memorial in early 1962, mandating that the property be relocated before a restoration could take place. That May, U.S. President
John F. Kennedy signed a bill to create the memorial, authorizing the
National Park Service (NPS) to take over the site from the ASHPS. Javits and U.S. Representative
John V. Lindsay estimated that it would cost the federal government $300,000–$400,000 to restore the Grange. When Congress had designated the national memorial, it had appropriated $460,000 for the house's restoration, of which $282,000 was for the relocation. A study by the ASHPS indicated that the house was structurally sound, and another report showed that the building could be moved if it were split into two pieces. Local residents organized in opposition to the relocation, and St. Luke's rector David Johnson did not want the house to be moved unless it was adjacent to the church. The house was partially restored during the mid-1960s, reopening in 1967. At the time, many of the house's original artifacts were stored in
Sagamore Hill. In its designation report, the LPC recommended moving the building to St. Nicholas Park so it could be fully restored. The report suggested that the house could be used to educate black students and that it could be renovated if Congress appropriated $500,000. The house was designated as part of the
Hamilton Heights Historic District in 1974. The Hamilton statue outside the house was cleaned in 1978. The Grange was closed for an extensive renovation in 1979. During its closure, the house was repeatedly broken into, although all the items in the house had been cleared out before the renovation. The firm of Meadows Woll Architects was hired in 1980 to study the feasibility of moving the Grange, The NPS announced in 1987 that the house would remain in place and would be renovated for $3 million. By then, the house was completely bare except for two side chairs and a piano in the octagonal rooms. Due to local opposition to the relocation, U.S. Representative
Charles Rangel wanted to change the law authorizing the Hamilton Grange National Memorial, allowing the house to be restored at Convent Avenue. and the
New York Post also agreed to donate some money for the house's renovation.
1990s By the early 1990s, the house had decayed significantly due to neglect and inclement weather. At the time, it had 40–50 thousand Georgette Nelms, the superintendent of NPS sites in Manhattan, began looking for contractors to stabilize the house's foundation in 1991. Severe deterioration forced the NPS to close the home to the public entirely in 1992. and he successfully requested another $1 million from the
United States Congress that October. The Hamilton Heights Homeowners Association held tours of historic houses in the area to raise money for the Grange's restoration. The Grange had few visitors and, according to Rangel, got less attention than
Grant's Tomb. Some local residents said the planned relocation of the Grange would disrupt the community; one group of opponents collected 1,200 signatures for a petition against the plan, The NPS planned to build a community center on the Convent Avenue site, but opponents remained skeptical. Supporters of the relocation said the Grange could not be restored at the Convent Avenue site. By 1995, the NPS was planning to seek $11 million from Congress. The NPS indicated that it would move the mansion to St. Nicholas Park, which not only allowed the house to be placed in a rustic setting but also occupied part of Hamilton's original estate. Congress gave around $1.5 million for the relocation, although the house needed another $9.7 million to fund the full project. The relocation process was delayed because the NPS did not have control of the St. Nicholas Park site; in the meantime, the agency spent $400,000 to stabilize the mansion. New York governor
George Pataki signed the bill in October 1999, allowing the New York City government to give the NPS an
easement within St. Nicholas Park to permit the Grange's relocation.
2000s renovation U.S. Senator
Daniel Patrick Moynihan wrote a letter to the NPS about the mansion's "deplorable" conditions in March 2000, and both houses of Congress passed legislation in late 2000 to permit the relocation. The NPS allocated $11 million to relocate the building in 2003. Hamilton Grange was closed to the public on May 7, 2006, to undergo architectural testing in preparation for relocating the house to St. Nicholas Park. Because the house was so tightly hemmed in by other buildings, the southern section of the house was disassembled first. The New York City government hoped that the relocation and renovation would attract visitors. The building was raised on hydraulic jacks over 20 days in 2008, with wood cribbing installed under the foundation. Hamilton Grange was raised to a height of about or . The house was then moved on rollers to wooden stilts in the middle of Convent Avenue; the stilts were disassembled, leaving the house resting on nine dollies by the end of May 2008. The NPS hired Wolfe House and Building Movers of Pennsylvania Before the house was to be moved, there were disagreements and legal disputes about its orientation. The NPS planned to rotate the house 180 degrees so it faced northeast; if the house retained its original southwest orientation, it would face a cliff in St. Nicholas Park. Everything in the house's path, such as street lamps and overhead wires, also had to be removed before the relocation took place. On June 7, 2008, the house was rolled half a block south on Convent Avenue and then one block east on 141st Street to the new St. Nicholas Park location over six hours.
David W. Dunlap of
The New York Times calculated its speed over the 500 feet at .04 mph. A group known as the Friends of Hamilton Grange filed a lawsuit over the house's orientation just after the house was moved but before it was placed on its foundation. The
New York Daily News reported that the relocation itself comprised approximately two-fifths of the renovation project's planned $8.4 million cost. After the house was secured to its new foundation, workers began restoring it. The federal government provided another $3 million in funding through a stimulus package. Restoration architects spent 18 months consulting documents to ensure that the restoration was historically accurate. and Fallon and Wilkinson were hired to create replicas of the original furniture. During the renovation, contractors rediscovered some of the original materials, using them to rebuild some of the original details.
Early 2010s to present The Grange reopened to the general public on September 17, 2011. A ceremony was held with Hamilton descendants in attendance and tours of the restored interiors. At the time of the reopening, only some of the first-floor rooms had been restored, while the second floor was closed.
Fergus M. Bordewich wrote in
The Wall Street Journal that the relocated house "will gaze out from its perch over one of the most vibrant black neighborhoods in America", namely Hamilton Heights. The house saw 21,000 annual visitors by 2014. and many people who saw the musical went to the Grange afterward. The house saw 35,000 visitors in 2015 and another 35,000 in the first five months of 2016, with a record 85,603 in 2017. , the site saw 63,647 visitors. ==Architecture==
