The Dover Days Festival is a 3-day celebration which features a huge parade, a car show, historical reenactments, music concerts and live shows, craft shows, food festivals, family events, and a lot more. The festival is held on The Green Mall and the Legislative Mall and attracts 25,000 people each year. In 2009, The Green was name one of the ten Great Public Spaces in America, which makes it a perfect location for the Dover Days Festival.

Held on the month of May, the Dover Days Festival is one of the longest running festivals in the country, considering that it first started in 1933. At first, the festival only featured a flower and garden show, but later became an annual tribute to the heritage of the people of Dover.
