Fort Massapequa is Revisited: John O'Halloran and Carlyle Smith 

(1953) 

Despite previous preservation efforts, the Fort Massapeag site faced a renewed threat in the 1950s: proposed street plans that would have cut directly through the historic earthworks, jeopardizing its protected status. 

• Rediscovery Efforts: Local preservationist John O'Halloran conducted crucial aerial surveys to accurately relocate the fort's embankment.

• Expert Mapping: O'Halloran enlisted archaeologist Carlyle Smith (who had surveyed the site in 1938) to return and meticulously remap the boundaries, strengthening the scientific case for protection. 

• Citizen Advocacy: A dedicated coalition of citizens, collaborating with local officials like John MacLean and George Peters, successfully blocked the developer's plans. Their advocacy led to a decisive victory: the Town of Oyster Bay agreed to purchase the property, securing it for permanent preservation.
