The forgotten tunnel under Brooklyn
A Diamond Below: “Unbeknownst to the thousands of people who walk and drive along the busy streets of downtown Brooklyn every day, they are treading on a 170 year old secret. At 17 feet high, 21 feet wide and 1,611 feet long, it is a big secret indeed, and one filled with greed, murder and corruption.”
Yet another place to visit! Via Kuutio.
