for one year. In the meantime, the city allocated $50,000 to shore up the fort's southeastern corner while the Brooklyn–Battery Tunnel was being built. In March 1948, a New York State Assembly committee refused to vote on a bill that would have allowed the federal government to take over Fort Clinton. Two months later, the Board of Estimate voted to demolish the castle for the sixth time. The American Scenic and Historic Preservation Society continued to advocate for the fort's preservation, asking the New York Supreme Court to restrict the city from demolishing Fort Clinton in July 1948. The state Supreme Court issued an injunction that December, requiring the New York City Art Commission to approve any proposal to demolish the fort, but the Supreme Court's Appellate Division struck down this injunction in March 1949. By early 1949, U.S. president Harry S. Truman had also expressed support for preserving Fort Clinton. The Assembly voted in March 1949 to cede the fort to the federal government, and the New York State Senate passed an identical bill. New York governor Thomas E. Dewey signed the bill the next month, allowing the city to transfer the fort to the federal government. Separately, the New York City Council voted to allow the New York state government to take over Fort Clinton if the federal government did not want to take over ownership. The U.S. House voted in October to allocate $165,750 for the fort's restoration, allowing the National Park Service (NPS) to start restoring the fort after the federal government gained ownership. The city's mayor William O'Dwyer supported the fort's preservation, but, due to legal technicalities, the city government did not transfer ownership of the fort for several months. On July 18, 1950, the city deeded the land and castle to the federal government. Federal government ownership The modern-day Castle Clinton is a one-story structure with a radius of . The roof above the fort's interior has largely been removed, and there is a nearly circular, open-air parade ground at the center of the fort. It is surrounded by a wall measuring thick. The stucco on the facade was removed under the National Park Service's ownership, and the brownstone-and-ashlar exterior walls were restored to their original condition. Underneath the walls is a rough stone foundation. The circumference of the fort contains a portico with wooden columns surrounding a canopy. There is also a gravel
