If we talk about downtown New York, in addition to the famous Wall Street and the bronze bull, Ground Zero is also a must-visit tourist attraction in New York. However, unlike other bustling places in New York, Ground Zero has a bit more historical significance. There is a huge square sunken pool with plaques around it engraved with the names of the victims. You can also see a lot of flowers placed next to the names as a memorial. There is also a bronze relief next to the World Trade Center site. If you have enough time, you might as well follow the navigation all the way. This is a 20-meter-long bronze relief built to commemorate the firefighters who bravely put out the fire in the 9/11 incident. Next to it are photos of the 343 firefighters who unfortunately died in the disaster, with the words "May we never forget", which makes people sigh at the preciousness and beauty of peacetime. Standing at Ground Zero, surrounded by towering skyscrapers, the contrast is very strong.
