[3] ComFest, a large, free, multi-day, non-corporate, music and arts annual festival, is held in the park in June.

[6] From April to June 1861, the park was used as a staging area for new recruits for the Union Army at the request of three city councilmen.

[6] The camp started in April when Governor William Dennison, at the urging of President Lincoln, called on Ohio communities to revive their militias and send them to Columbus.

The Governor's Guards, a corps of soldiers stationed at the camp, marched through Columbus on a Saturday morning to urge the local people to show their patriotism and enlist in the cause.

"Any young man interested in enlisting in this company, "B" of the 3rd Regiment, is told to call at Camp Jackson at an early hour."

[3] After the Civil War, the park was under construction until 1875 for the creation of a carriage drive, landscaping inspired by Andrew Jackson Downing, and a lake house.

[6] In July 1910, the park once again hosted troops when the Ohio National Guard was called in to quell a streetcar strike when it looked to turn violent.
