Central Park is bringing back its big guns.
For most of the 20th century, two 18th-century cannons graced a bluff in the park that overlooked Harlem Meer. They survived a mysterious sinking off Hell Gate of a British frigate reputedly laden with gold, the Revolutionary War, the War of 1812 and a fire at a museum near the Conservatory Garden. But during the cityâs 1970s fiscal crisis, the weapons fell victim to vandalism and neglect.
Hustled off to a warehouse on Randalls Island, the cannons have not been seen by the public for decades. Now, Central Parkâs only heavy artillery is being conserved and is expected by this summer to be installed, once again, at the promontory overlooking Fifth Avenue at 106th Street.
The reconstruction of Fort Clinton and Nutterâs Battery Overlooks, by the Central Park Conservancy and the parks department, was approved recently by the cityâs Design Commission. While the histories of those former military fortifications were fairly well established, the provenance of the cannons was considerably murkier.
They were originally thought to have been installed to protect the city from a British invasion launched from Long Island Sound during the War of 1812. But an authoritative account by Sara Cedar Miller, a historian for the conservancy, dates the big guns back more than 240 years to the 28-gun HMS Hussar commissioned in England in 1763. (Actually, only one is an actual cannon. The other is a cannonade or mortar.)
Attached to the British fleet in New York, the Hussar ran aground in treacherous East River currents in 1780 and sank. Because it was believed to be carrying an army payroll made up of gold, for more than two centuries the ship has attracted salvage efforts, which retrieved no gold but, among other artifacts, the two cannons, which â" after languishing in salt water for as long as 80 years â" were anonymously donated to Central Park in 1865 while it was still under construction.
The artillery was originally displayed at the Arsenal, now the Parks Department headquarters on Fifth Avenue at 64th Street, and later at a museum in the former chapel of the Mount Saint Vincent convent at 105th Street. The museum burned in 1881. The cannons survived, although their whereabouts for the next two decades is uncertain.
They re-emerged in 1905 when the American Scenic and Historic Preservation Society, founded by Andrew Haswell Green, persuaded the parks department to install them at the site of Fort Clinton. This was originally called McGownâs Pass, a British fortification built during the Revolutionary War and then rebuilt during the War of 1812, when it was renamed to honor Mayor DeWitt Clinton.
The cannons perched on a granite base (with a plaque that wrongly attributed their origin to the War of 1812) until the 1960s or â70s.
âThe empty chunk of granite where they had been positioned symbolized and coincided with the loss of New York Cityâs fiscal power to maintain its park and its historic monuments,â Ms. Miller wrote.
The Central Park Conservancy retrieved them in 1996. Last January, while removing centuries of rust, two restorers discovered that the mortar contained a cannonball and live ammunition. The police bomb squad was summoned.
The cannons will be reinstalled at Fort Clinton. Even though that is not where they originated, their placement, within sight of where the Hussar sank, seems appropriate.
âIndeed,â Ms. Miller wrote, âBritish soldiers probably viewed that disaster through their spyglasses from the very spot where the cannon and mortar will once again be placed.â
