There are so many interesting things to see in New York City. This pier for instance, if you look at the details in the architecture you can see it's quite old and a big contrast from the modern sky scrapers in the background. This contrast between historical and modern can be seen throughout the city.
Personally, I find the historical structures so much more interesting. However, it's also kind of a testament showing the constant change co-existing with what has endured for a century.
