Egyptian Revival Architecture is like playing dress-up for buildings. Just like when you put on a costume and pretend to be someone else, buildings built in the Egyptian Revival style pretend to be from ancient Egypt.
In ancient times, the Egyptians built giant pyramids, temples, and statues with lots of decorations like hieroglyphics and sphinxes. A long time after the Egyptians, people in other countries thought it was cool and wanted to create their own buildings that looked like they were from ancient Egypt.
So in the 19th and early 20th centuries, architects designed buildings with big columns, exotic shapes, and hieroglyphics that imitated the ancient Egyptian style. They used materials like stone and metal, painted everything in bright colors, and sometimes even included statues of pharaohs or Egyptian gods.
Some famous examples of Egyptian Revival Architecture are the Luxor Hotel and Casino in Las Vegas, the Palace of Fine Arts in San Francisco, and the Egyptian Avenue in London's Highgate Cemetery.
So if you ever see a building with columns shaped like papyrus stalks, or decorations that look like they were taken from an ancient tomb, you might just have found a piece of Egyptian Revival Architecture!
