Overview
The Emerald City (sometimes called the City of Emeralds) is the capital city of the fictional Land of Oz in L. Frank Baum's Oz books, first described in The Wonderful Wizard of Oz (1900).
Fictional description
Located in the center of the Land of Oz, the Emerald City is the end of the famous yellow brick road, which begins in Munchkin Country. In the center of the Emerald City is the Royal Palace of Oz. The Oz books generally describe the city as being built of green glass, emeralds, and other jewels.
In the earlier books, it was described as completely green. However, in later works, green was merely the predominant color while buildings were also decorated with gold, and people added other colors to their costumes.
In The Wonderful Wizard of Oz (1900)
In the first book, The Wonderful Wizard of Oz (1900), the walls are green, but the city itself is not. However, when they enter, everyone in the Emerald City is made to wear green-tinted spectacles. This is explained as an effort to protect their eyes from the "brightness and glory" of the city, but in effect makes everything appear green when it is, in fact, "no more green than any other city". This is yet another "humbug" created by the Wizard.
