In 1986, many unused remaining structures built for the fair were removed and in celebration of the 20th Anniversary of HemisFair '68, approximately of the site were redeveloped with cascading waterfalls, fountains, playgrounds and lush landscaping. Many of the improvements were concentrated near the base of the Tower of the Americas. At the site's re-dedication in April 1988, the site was re-christened "HemisFair Park". This urban park is a lasting legacy of the fair and is a gift from the city to its citizens.
