The Carlton County Courthouse in Carlton, Minnesota, United States, is the county seat of Carlton County, Minnesota. The county seat was originally located in Cloquet, with a jail located at the town of Northern Pacific Junction. In 1890, residents of Northern Pacific Junction raised funds to build a courthouse, which was a two-story brick building with a high-pitched gable roof. The current building took about two years to build, being completed in 1924. It is a three-story building with cream-colored brick and stone.
The Carlton County Vidette praised Clyde Kelly, the architect, with these words: "Unquestionably, the man who assumes the responsibility of being the architect for a building like this is entitled to great consideration. To him is left the superintending of the placing of every stock and stone in the building ... to make the structure as perfect as possible."
