ARCHITECTURE: Changes Over Time

This image actually combines both nature and architecture and represents the changes which took place on the surface of the Earth over time. The left side of the picture shows the Earth's surface before the appearance of human species. After that humans started being engaged with rural activities and building their first houses and castles. Then the industrial revolution started and many industries were built. The right side shows how Earth changed after millions of years of human development.

My creation was actually slightly bigger but I had to crop it in order to fit the puzzle's size.
