Did you know that world's official oldest subway tunnel is located right here in New York in the borough of Brooklyn?  Yes, indeed!  It's the Atlantic Avenue Tunnel, built in 1844.  This is fascinating!

What's even more amazing is that one can take a tour of this tunnel.  Once a month (usually on a Sunday), via The Brooklyn Historic Railway Association, hour and half tours are conducted and narrated by Bob Diamond who actually re-discovered the tunnel in 1980.  Way to go Bob!

Adults pay $15 while children pay $10.  It is for a good cause, especially since The Brooklyn Historic Railway Association is a non-profit organization.

Be forewarned, to enter the tunnel, one must climb down a manhole located in the middle of the street.  I actually think that's a bit adventurous!

The next tour takes place on May 16, 2010.  To register and find out about future tours, see images of previous tours and to discover fun facts about the history of Brooklyn's great railway system go to: http://www.brooklynrail.net/bhra_events.html
