The Roslyn Landmark Society announced today a grant award totaling $427,000 from the New York State Council on the Arts (NYSCA) to support the organization’s Mackay Estate Gate Lodge Roof Replacement. This grant is part of a capital project funding announcement by NYSCA, which totals over $86 million to 134 capital projects across New York State.
Built between 1900-1902, the Mackay Estate Gate Lodge is architecturally significant as an example of the Beaux-Arts design of Stanford White, one of the most prestigious architects active in the United States during the Gilded Age. This extraordinary structure once served as the grand entry point to Clarence Mackay’s "Harbor Hill," one of Long Island’s most magnificent “Gold Coast” era estates. The Gate Lodge is one of only three of the estate’s original structures still standing. Since 2022, the Roslyn Landmark Society, in partnership with the Village of East Hills, has been working to restore it to its former grandeur.
“We are extremely grateful to be recipients of this funding from the New York State Council on the Arts (NYSCA), as it will assist us in continuing to restore and preserve this unique representative structure of Long Island’s Gilded Age history,” said Jaime Karbowiak, executive director of the Roslyn Landmark Society. “The repair and replacement of the building’s slate roof, which this grant award will be instrumental in completing, will bring us one step closer to revitalizing this rare historic site into an education center and community space for the public.”
“Our arts and culture sector is a powerhouse, inspiring the world with innovation and creativity,” Governor Hochul said. “By investing in our museums, our theaters and our arts centers, we enrich our communities, strengthen local economies and improve tourism all over the State.”
NYSCA Executive Director Erika Mallin said, “These transformative projects improve communities, drive tourism and foster innovation in the field. Thanks to the Governor and the Legislature’s dedication to arts and culture, we are building a thriving future for our world-renowned creative sector. Congratulations to the Roslyn Landmark Society, NYSCA is a proud supporter of your contributions to New York’s arts and culture.”
