History
Carroll County was created on January 15, 1851. It was named after Charles Carroll of Carrollton, a famous signer of the Declaration of Independence. He was also the only Roman Catholic signer.
In 1855, the county government started in a town called Carrollton. Three years later, in 1858, the first courthouse was built there. A courthouse is where important county decisions are made.
Later, in 1869, the main town moved to Carroll City, which is now just called Carroll. This new location was better because it was in the middle of the county. It also had a connection to the railroad, which helped people travel and trade.
Sadly, the courthouse burned down in 1886. The building you see today was built in 1965. It helps the county government serve the people of Carroll County.
