The cities history started in 1912 when Charles C. Chillingworth and his Palm Beach County Land Company (at the time the area was part of Palm Beach County) bought property from original owner George Beckwith and advertised the land throughout the United States, Canada and Europe. Pineapples, oranges and grapefruit were grown at a "Demonstration Farm" on present-day Martin Highway to show farmers what they could expect if they settled in the newly named Palm City. Chillingworth provided boats, mule-teams and covered wagons (later replaced by a Model T Ford) to take the prospective clients around the undeveloped countryside.

An advertisement in the Palm Beach County newspaper boasted "Free dinner on New Year’s Day for prospective buyers. A 10 acre tract for $50 per acre (to be raised to $60 the next day) with a free town lot in Palm City to every purchaser and 85¢ for a round trip train ticket from West Palm Beach to Stuart." The Palm City Farms offered by Mr. Chillingworth’s Palm Beach Land Corporation were sold to many people over the entire country, sight unseen.

The Palm City Chamber of Commerce currently owns and operates in the original building known as The Palm Beach Land Company Real Estate Office.

Palm City is a peaceful community. Stuart sits on Florida’s central Treasure Coast on a peninsula that juts out into the St. Lucie River. This compact little town has a remarkable amount of river shoreline for its size and also a charming historic downtown district. Here, the golf and tennis are great and the fishing is legendary. Fish abounds in the fertile waters of Palm City . You can spend the day fishing from the docks or offshore for snook as well as seatrout, kings, mackerel, grouper, snapper and wahoo. If golf is your game, thirty-six holes of championship golf surround the community, and you can also take advantage of several tennis courts and Olympic sized pools. Horseback riding, bicycle riding, hiking and nearby river access is also available. The West Palm Beach International Airport is an easy 45-minute drive away, and two hours takes you to Disney World and Sea World. Palm City offers a pristine environment where you can escape the crowds and relax in the peace and quiet of nature, with all the conveniences of home.
