My third day in the city was full of sight seeing. After heading down to Ground Zero the day before and finding out you needed a ticket to see the pools, I returned ticket in hand to see the site of the Twin Towers. Each tower's base is now immortalised with the biggest man-made pools in history, with every victim's name etched in the surrounding plinths. I knew it was going to be emotional, but I didn't realise how overwhelming it would all be standing where nearly 3000 people lost their lives. Looking up at the towering buildings around the site, you can't even imagine a plane flying into one and sending it toppling down. The site itself is very peaceful and I'm sure a welcome space for friends and family members to reflect upon their lost loved ones - a definite must-see if you're visiting the city. The next stop on my tour was the New York City Public Library; not only is this an iconic building facing 5th Avenue, but it's the sight where Carrie and Big were supposed to get married in SATC! You can walk up the same steps and take in the marble surroundings, visit the reading rooms, have a look around the exhibitions and even take a peek where some of the world's most famous books are stored. I sat at the bottom of the marble stairs for ages, chilling out away from the madness of 5th Avenue, before wandering down to the Rockefeller Centre to step up to Top of the Rock. This gives a much better view of the city than the Empire State Building, mainly because it's located further uptown and allows you to see Central Park from one side, as well as the Empire State itself downtown. There are three different viewing platforms and the tallest is open so you can see the sights without pinning your nose up against a plastic wall! Unsurprisingly it's really chilly up there and I got a bit windswept, but the views are totally worth it - you get a real sense of scale and the towering buildings really make you feel like a little person in a big bold city.
