The history of Mount Dora dates back to the mid-19th century. Initially, the settlement was known as Royellou—named by the first postmaster after his daughter. The town officially received its current name in 1883, and its etymology directly reflects the unique geographical features of the area.
The town's name is composed of two significant elements:
- "Mount": Refers to the town's location on a plateau 184 feet (56 meters) above sea level, which is an unusually high point for the predominantly flat state of Florida.
- "Dora": Derived from Lake Dora, which in turn was named by surveyors after Dora Ann Drawdy, one of the first pioneers who lived here in the 1840s.
A key moment in the town's development was the arrival of the railroad in 1887, which served as a powerful economic stimulus, allowing for the export of goods and the arrival of travelers. Thanks to its hilly landscape, picturesque lakes, and favorable climate that encouraged the planting of vast orange groves, Mount Dora quickly transformed from a modest settlement into a thriving town.
By the end of the 19th century, Mount Dora began to cultivate its image as an elite vacation spot, becoming a popular winter resort for residents of Northern states, hunters, and fishermen. In 1883, the famous Lakeside Inn was opened; it remains in operation today as the oldest continuously operating hotel in Florida. Many buildings from that period, constructed in the Victorian style, have been preserved to this day, giving the downtown area its recognizable historical charm.
