- Emerald City is a fictional city in the Land of Oz, a world created by author L. Frank Baum. It is the capital city of Oz and is known for its beautiful green buildings and streets, which are made entirely out of emeralds. The citizens of Emerald City, including the Wizard of Oz, wear green-tinted glasses to protect their eyes from the city's dazzling emerald radiance.
- In Baum's original novel "The Wonderful Wizard of Oz," Emerald City is described as a magnificent and opulent place where everything is green. The city is ruled by the celebrated and mysterious Wizard, who resides in the Emerald Palace at the city's center. Visitors to Emerald City must first pass through its impressive gates and are required to wear green spectacles to maintain the illusion that everything is green.
- Emerald City has been featured in various adaptations of Baum's original novel, including the famous 1939 film "The Wizard of Oz." In these adaptations, Emerald City is often portrayed as a place of great splendor, with grand architecture and a central emerald palace that glimmers in the sun.
- The concept of Emerald City has also become a symbol of something that is beautiful and precious. It is widely used as a metaphor for a place of wealth, power, or utopian ideals.
