In less than 200 years, America has become one of the greatest powerhouses the world has ever seen. Since the days of George Washington crossing the icy Delaware River to help secure our independence, America has gone through drastic changes, probably greater than any other country during the same time period. Urbanization took the United States by storm in the mid 19th Century, with many families and immigrants flocking to big cities on the east coast such as New York, Boston, and Philadelphia. As time went on, more major cities began popping up on the map, such as Miami, Chicago, and Los Angeles, all becoming extremely popular spots. Urbanization only continued to increase through the 20th century, and society is currently in a time where it is difficult to imagine what life must’ve been, and looked like back in the days before we had massive skylines completely lit up at night. This is a gallery so you get a good understanding of what America had to go through to get all of it’s beautiful skylines, and remarkable landmarks.
