One World Trade Centre Nestled next to where the twin towers used to stand is the magnificent one world trade centre, one of the tallest building in the world and extremely pretty too. I loved how the mirrored glass encasing the building reflects the blue sky and fluffy white clouds, it’s very impressive and a great monument to stand in the place of the twin towers. We were lucky enough to to go up to the observation deck and I will share the photos of the amazing views across Manhattan and the Hudson River with you all a little later today.
