Large labia

Jeju Loveland (제주러브랜드) (also known as Love Land) is an outdoor sculpture park which opened in 2004 on Jeju Island in South Korea. The park is focused on a theme of sex, running sex education films, and featuring 140 sculptures representing humans in various sexual positions. It also has other elements such as large phallus statues, stone labia, and hands-on exhibits such as a "masturbation-cycle." The park's website describes the location as "a place where love oriented art and eroticism meet."
