Dunsan Grand Park, designated as an urban neighborhood park on June 7th, 1991, is a local cultural Mecca. The park is home to a wide variety of cultural and arts facilities including the Daejeon Culture & Arts Center, Pyeongsong Youth Cultural Center, Daejeon Museum of Art, and Ungno Lee Museum of Art. Coupled with the arboretum, it is one of the most culturally sophisticated areas of the city.The Hanbat Arboretum, linked with the Government Complex-Daejeon and Science Park, is the largest manmade urban arboretum. This venue serves multiple purposes: to act as a reservoir of genetically diverse foliage, an eco learning center for students, and a recreational area where people can relax and pass the time in the peaceful embrace of nature. The arboretum, standing on a lot measuring 387,000m2 (1,270,000ft) was developed as part of a three-stage plan. Seowon (West Garden, located north of the Daejeon Museum of Art) and Nammun Square opened on April 28th, 2005, while Dongwon (East Garden located north of Pyeongsong Youth Cultural Center), which consists of 19 uniquely themed parts such as the Magnolia Garden, Medicinal Herbs Garden, Rock Garden and Fruit Garden, opened on May 9th, 2009.
