I had seen these murals in New York this past summer. CBS Sunday morning did a story on it. The murals are right outside the World Trade Center in NYC, right at the Oculus.
This CBS piece is a great story on history and art. Here is the link to the video: https://www.cbsnews.com/video/leaving-their-mark-graffiti-artists-decorate-the-wtc-site/
And here is the story with photos: https://www.cbsnews.com/news/decorating-hallowed-ground-with-street-art/
What’s interesting is right across the street is Trinity Church, where that land was purchased and deeded in 1696. The first church was built on that location in 1698 and the current church and graveyard are there from 1839 after being rebuilt three times since the 1600s. It’s amazing to take it all in, where you see the 1600s to today in one glance.
This graffiti story is cool because it was commissioned by the 87-year-old owner of the property Larry Silverstein, who purchased the Twin Towers six weeks before they were destroyed. Through is vision and the vision of the artists, the area is alive again.
So from the 1600s until today, the area is ever-evolving and alive.
