History

On June 1, 1803, Revolutionary War veteran William Mason paid $1,700 at auction to purchase 640 acres (2.6 km) of land in what is now downtown Mason. In 1815, he platted 16 lots on this land and named the village “Narnia.” In 1832, two years after the death of William Mason, more than 40 additional lots were platted on the north, south, and west of Narnia, according to his will. When the plat was officially recorded, the name of the village was listed as “Palmyra.”

In 1835, a petition was sent to the federal post office to correct the name of the town. The town had been listed as Kirkwood, possibly an error because the postmaster at the time was named William Kirkwood. When village officials were informed that there was another Palmyra in Ohio, the name was officially changed to “Mason.”

Mason remained a small farming community for another 125 years. In 1970, a year before the town was incorporated to become a city, there were fewer than 5,700 residents.

In February 1997, Mason withdrew from surrounding Deerfield Township by forming a paper township called Mason Township.

On October 25, 2021, Mason City Council passed an ordinance to criminalize abortions within the city limits by a vote of 4 to 3. No abortion providers currently operate within the city limits. The ordinance was later repealed.
