The way places and views look changes a lot over the years. What places looked like decades ago are not how they appear today. This is due to a rise in population and an evolution in technology. Technology has advanced, buildings have been built, and cities have expanded greatly. Many major cities, historical sights, and other popular places have altered in appearance drastically. It's interesting to see how time has affected these spots.

The huge skyscrapers across New York were once never there. All of the hustle and bustle in Vegas was once nonexistent. Some buildings that are empty and abandoned were once busy places to be. It's weird to see just how quickly everything has changed in such major ways.

There are tons of photos online of cities, historical buildings, and other famous sights from the past compared to now. Here is a collection of 25 side-by-side photos of how places looked way in the past and how they look today.
