Drones explore abandoned Bannerman Castle located in the Hudson River in upstate NY.

Pollepel Island has been called many different names, including Pollopel Island, Pollopel's Island, Bannerman's Island, and Bannermans' Island. The name is a Dutch word meaning "(wooden) ladle," but the Bannerman Castle Trust organization ascribes the name to a folk tale about a young girl named Polly Pell having been stranded on the island.

The island is about 50 miles (80 km) north of New York City and about 1,000 feet (300 m) from the Hudson River's eastern bank. It contains about 6.5 acres (26,000 m2), most of it rock.
