Art Around City Hall Park on View

Should you be assigned jury duty (you're a New Yorker) or should you be a tourist wanting to cross the Bklyn Bridge or view public art works, visit City Hall Park to enjoy public artworks & historic landmarks.  Behind the Court House, on a shady promenade with benches, there is a humongous "Caldor" like sculpture painted all in red, constructed of combined circular forms.  It is almost graffiti-free (not the wisest place to mark public property) if you wish to remain discreet.  However, there are some stickers high-up one side:  a black/white sticker "Vans off the Wall."  I have no idea, but there is a sticker with 3 peace symbols in red, green & yellow.  I didn't find a placque with information regarding an artist, etc.  I did observe a nimble, young boy climbing up the sculpture calling out for his mother to watch.  Nearby is a prison window built in 1763 used by the British during the Revolutionary War.  The prison was demolished in 1892.  The window was claimed as a historical artifact.  (It does have a cross emblazoned on the plaque.)  While on jury duty I was pleased to note when being sworn under oath, the word God is no longer included.  However, in the jury pool room, in large letters on the wall are the words "In God We Trust." This phrase is found on all our printed currency.  A woman is about to be featured on the $10 bill.  Perhaps, court houses & currency should be made current by striking these words from government institutions.
