Before the fair, the site was used as a railroad yard. The land was converted into park space for the 1982 World's Fair. In 1991, the U.S. Pavilion was demolished by implosion due to structural damage caused by neglect. In 2007, the Sunsphere began to see occupancy. Today, it currently houses offices and a public observation deck. In 2019, the park's performance lawn closed for a $3 million renovation, and reopened later in July of the same year. In 2019, the
Knoxville Marathon's finish line was relocated to the park, due to renovations at
Neyland Stadium, the location of the original finish line. ==Gallery==
