The Presque Isle County Fair was started by the Presque Isle County Agricultural Mechanical Society and was first held on September 25 and 26, 1901 in Millersburg. Sometime around 1932 the fair moved to Onaway. After a stop at Posen as a 4-H fair and the Moltke Township Hall where it was held for about eight years, the year 2000 saw plans made to move the fair back to Millersburg. The first fair back at its original location was held in 2001.

The improved fairground has a 30' x 96' animal barn. There is also a grandstand with banked seating for about 800 people where main events are held. Both were constructed in 2005. A new announcer's booth was built and 2 new P.A. systems were purchased to complete the area. Spring of 2006 brought the addition of a beautiful new sign at the main entrance of the fairgrounds! Permanent fencing around the drive to help with crowd control and parking was installed in 2007. Water lines were buried and electricity has been update to handle to amusement rides and venders. Outside lighting was added for evening events.
