The Janssen Park measures about ten acres that serves as home to two tiny lakes, an enclosed section for deer along with an ancient log cabin that dates back to 1851. That cabin was known to be used as an official hideout by the ever notorious icon of the Wild West Jesse James. It was then used as city hall, post office and hospital.

The park was created from a city donation led by Arthur Sitwell along with his other associates who serve to be the founders of Mena too. In 1906 it was a park for exclusive use. The old log cabin was made by William Shelton to serve as his own home that time. And when Mena was starting to be laid out as a city, it was used by the town site company.
