The Former Audubon County Courthouse, also known as the Audubon County Historical Society Museum, is a historic building located in Exira, Iowa, United States.
 Court proceedings were first held in a schoolhouse in Hamlin’s Grove after Audubon County was established in 1851.
 The county seat was relocated to Exira ten years later, and a disagreement erupted over where the county seat should be located.
 The county board of supervisors made an appropriation for a new courthouse in 1871, but its construction was delayed due to the disagreement.
 Exira eventually won and officials constructed the courthouse for about $2,200.
 The Exira Hall Company was established to build the two-story, frame structure.
 County offices were located on the first floor and the courtroom was located on the second floor.
 The county seat was moved to Audubon in 1879.
Lancaster School is located in rural Keokuk County, Iowa, United States southeast of the county seat of Sigourney.
 It is the last public building in what was the former county seat of Lancaster.
 It occupies the ground that was the courthouse square.
 The school was one of six two-story buildings built by the county for educational purposes in the 1870s and early 1880s.
 They required two teachers, and were therefore more expensive to operate.
 This building was constructed in 1881 by Reynolds Bros.
 It replaced a school building that had been built further east in 1874.
 It is a two-story frame structure that measures 33 by .
 The pedimented entry faces the south, and there is a belfry above the gable.
 A single classroom is located on the northern two-thirds of both floors.
 The town of Lancaster at one time had 32 buildings, but it started to decline in the 20th century.
 Enrollment in the school was 119 in 1898, but fell to about thirty early in the 20th century.
 When it closed in 1964 there were 13 students enrolled, and by that time they only utilized the first floor.
 The former school building, one of the churches and a few houses are all that remain of Lancaster.
 The building has been used in subsequent years as a voting facility.
 It was listed on the National Register of Historic Places in 1984.

The Johnston Library is a historic library located at 210 W. 10th St. in Baxter Springs, Kansas.
 The building was constructed in 1872 to serve as a courthouse during Baxter Springs' unsuccessful attempt to become the Cherokee County seat.
 Though Baxter Springs had lost an election to choose the county seat in 1869 to Columbus, supporters of both cities had attempted to fraudulently swing the election in their favor, and Baxter Springs hoped it could still become county seat in the future.
 The building initially served as the county jail and sheriff's office until Columbus completed its jail in 1880.
 After this, Baxter Springs ultimately gave up its attempts to become the county seat, and the building became its city hall.
 In 1905, resident Niles P. Johnston bequeathed $5,000 to the city to start a library, and the city hall building was chosen to house it.
The Gardnerville Branch Jail is a historic jail located at 1440 Courthouse St. in Gardnerville, Nevada.
 The jail was built in 1910 and served as Douglas County's only jail from 1910 to 1915.
 Prior to 1910, the only county jail was in Genoa, the county seat; however, since Gardnerville was several miles from Genoa, it resorted to housing prisoners in the local judge's granary.
 As the granary was considered unfit for holding prisoners, the community petitioned the county to construct a new jail.
 However, local leaders in Minden, who wanted to move the county seat to their town, protested the move, as they suspected that Gardnerville was attempting to claim the county seat itself.
 Nonetheless, the county approved the construction of the new jail.
 The jail housed its first prisoners before construction even finished, as the Genoa jail burned down; one prisoner was briefly chained to a post until the new jail could accommodate him.
 Once completed, the jail served the county until 1915, when Minden became the county seat and opened its own county jail.
