Martin County Courthouse

The Martin County Courthouse is the county courthouse for Martin County, Minnesota. The building is located at 201 Lake Avenue on the western side of the city of Fairmont, on a hill overlooking Lake Sisseton. It is a Beaux Arts building featuring a high copper dome with four clock faces. The first floor was made out of Michigan sandstone. The second and third stories are built of Bedford limestone. The arched entrance is flanked by polished double Corinthian order columns and topped by a pediment.

The building is connected to the brick and concrete Martin County Security Building by sky-way on second level, and by tunnel below ground, at basement level. The security building provides space for police and detention, and was designed by 1972.
