New materials and techniques along with more creative minds have evolved architecture over time. To view a difference in architecture, one can analyze the differences between European architecture and North American architecture; more specifically, the architecture between Paris and New York City. These two metropolises represent diversity and a rich sense of history that is evident in their architecture.

New York City and Paris vary in many ways; however, they are both architectural hubs of the world. Both of these cities attract architects trying to make their mark and promote development in terms of architecture. On the other hand, both cities offer completely different styles of architecture to the everyday person. For instance, New York City (NYC), being built on a bedrock foundation, has over 100 skyscrapers, whereas Paris, being built on limestone (Noe), has only a few buildings over 37 meters (Karmelek). One crucial difference between the two cities is the materials that makeup the structures. In Paris, stone is commonly used, while in NYC, the skyscrapers are composed of steel. This allows for the buildings in NYC to be built much higher while their counterparts in Paris can only build to a maximum height of 37 meters due to zoning.

Examples of notable structures in Paris include the Notre-Dame Cathedral and the Eiffel Tower (Encyclopedia Britannica). While the Eiffel Tower compares easily to the skyscrapers in New York, it stands out in Paris due to its immense height. In NYC, the Empire State building and the Chrysler building are featured representing the art deco style and showcasing the use of steel.

Although these cities and their buildings are different in their architecture, they both represent the culture they are immersed in. If an observer looks closely, he or she will notice that all architecture has the same foundation and principles. This is important for those studying architecture in its various forms.
