Clearing the smoke of the legend and speculation, the long-lost Cobble Hill Subway Tunnel was rediscovered years ago by Brooklyn urban explorer and transit enthusiast Bob Diamond.
Located under Atlantic Avenue in Cobble Hill, Diamond proved many experts wrong when he investigated the tunnel himself, and rediscovered the first subway tunnel ever built in America. Many came for Diamond’s official tours of the tunnel to investigate the mystery for themselves, but returned time and time again for the draw of Diamond’s surreal discovery story. Diamond is no longer allowed in the tunnel, outraging many as he had 32 years with not a single incident.
