Prince Frederick is located in the center of Calvert County. Prince Frederick has served as the county seat of Calvert County since 1722, when officials chose a plot of land known as “Williams’ Old Field” as the spot for the new county courthouse. (Contemporary references to the piece of land include an upscale dining restaurant named Old Field Inn, and a street in Prince Frederick named “Old Field Lane.”) The original courthouse was finally completed in 1732. The town was most likely named for George II’s son Frederick, who was Prince of Wales during the time of the town’s original conception.
Prince Frederick is Calvert County’s main commercial and retail hub, as it contains at least five major shopping centers, numerous chain and independent restaurants, three hotels, and Calvert County’s only movie theater.
Notable places in the Prince Frederick area include Battle Creek Cypress Swamp—a local nature preserve—and the Arthur Storer Planetarium, which is located on the grounds of Calvert High School. The Calvert County Fair is held every fall at the Calvert County Fairgrounds just outside Prince Frederick. The fair moved from its original location in downtown Prince Frederick in 1994.
