Mason is a city in southwesternWarren County, Ohio, United States. The population was 34,792 at the2020 census. Located approximately 22 miles (35 km) north of downtownCincinnati, it is home toFortune 500 corporationCintas, theKings Island amusement park, and theLindner Family Tennis Center, home of theCincinnati Open.
On June 1, 1803,Revolutionary War veteran William Mason paid $1,700 at auction to purchase 640 acres (2.6 km2) of land in what is now downtown Mason. In 1815, he platted 16 lots on this land and named the village "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."
In 1923, Main Street was paved, prompting a celebration throughout the town.
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.[5]
In February 1997, Mason withdrew from surroundingDeerfield Township by forming apaper township called Mason Township.[6]
In 1928 the 50,000 watt, 831-footWLW-AM tower was built on Tylersville Road. Six years after its construction, PresidentFranklin Roosevelt ordered the station's equipment be upgraded to operate at 500,000 watts, making it the most powerful broadcast station in the country at the time, powerful enough to broadcast across the Atlantic ocean. This proved bothersome for locals, as they could hear the broadcast through their bedsprings, downspouts, and fencing.
In 1939, after complaints from other radio stations due to signal interference, the power was reduced back to 50,000 watts after the Federal Communications Commission chose not to renew the station's experimental broadcasting license. This decision was appealed by theCrosley Corporation, the company who operated the tower, and taken all the way to the Supreme Court, where it was denied.
According to theUnited States Census Bureau, the city has a total area of 18.67 square miles (48.36 km2), of which 18.63 square miles (48.25 km2) is land and 0.04 square miles (0.10 km2) is water.[7] The city has a short border along theLittle Miami River.
