In the center of Oakland, and completely surrounded by it, is the prestigious city of Piedmont.  Piedmont is primarily a residential area full of grand, spacious estates and charming bungalows.  The city boasts award winning public schools, great parks and top-notch city services.  Due to its school system, low crime rate and good weather it is regarded as one of the most desirable residential communities in the San Francisco Bay Area.  Property in Piedmont is markedly more expensive than real estate in neighboring communities.  Piedmonters have an exceptional spirit of volunteerism and serve on many committees, commissions and boards.
In the 1920's, Piedmont was known as the "City of Millionaires" because there were more resident millionaires per square mile than in any city in the United States.  Many of these millionaires built mansions that still stand today.
Piedmont is largely zoned for residential use.  It has one intimate commercial district in the center of town along Highland Avenue consisting of a gas station, three banks, some professional offices and a small upscale market.
