What drives Mount Dora’s History grade
On its age, its old homes and the National Register, Mount Dora is more historic than 61% of U.S. towns, #38 of 638 in Florida. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.
B
HistoryA character grade: shown, never part of Mount Dora’s overall grade.
Few Florida towns list much on the Register (a typical Florida town has 0.0 per 10,000 residents, the U.S. 2.4), so Mount Dora’s 331 sits above most of its state (99% of Florida towns have fewer) while its 572 historic buildings outnumber those of 98% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C to B+. The pre-1940 share (±1.9 points) is firm at this size. The founding year is the first post office, not a stated founding date.

The town of Mount Dora began in 1874 when the area was settled by David Simpson, his wife, and two children. In 1880, Ross C. Tremain became the town's first postmaster, and later a major real-estate developer for the area. A post office called Mount Dora has been in operation since 1883. Tremain named the unincorporated village Royellou, after his children, Roy, Ella, and Louis. The community was renamed for Dora Ann Drawdy, who was an early settler of the town in the mid-1880s. In 1846, the surveyors named Lake Dora after her, and in 1883, the town was renamed after the lake. The Mount in Mount Dora reflects the fact that the town is on a plateau 184 feet above sea level. In addition to this, Dora is memorialized through Dora Drawdy Way, an alleyway located in the downtown area. The town’s original name is honored in a similar fashion through another alleyway simply named Royellou.
