Dexter is home to the historic Dexter Community Building (aka Dexter Roundhouse) which was completed on March 1, 1917 and is believed to be the first building of its kind on the American continent. Dexter Park, which is located between Dexter and Redfield, was the site of the famous Bonnie and Clyde Barrow Gang shoot out in 1933.
