Stony Batter is a historic site on Waiheke Island, Auckland, where gun sites and other remains from World War II stand. The site is known locally as a boulder field, and its listing describes the gun sites and other remains as impressive.
Stony Batter lies on Waiheke, an island in the Hauraki Gulf reached by ferry from central Auckland. For visitors interested in the island's wartime past, the site is the place where the remains of those defences can be seen.
