Vigeland Park is the world's largest sculpture park dedicated to the work of a single artist, and an ode to one man's obsession with the human form. The park displays over 200 sculptures fashioned from granite, bronze and wrought iron by the Norwegian artist, Gustav Vigeland, created over a period of 20 years from 1924 to 1943. In fact, the park itself was designed by the famed sculptor and is actually a mammoth installation in Frogner Park. Vigeland's work varies from depictions of humans engaged in everyday tasks, to more symbolic and abstract works like The Monolith, a 14.12-meter (46.33-foot) high sculpture composed of 121 human figures intended to represent the human desire to reach out to the divine. Other notable sculptures include The Wheel of Life and The Fountain. Although each is a masterpiece in its own right, the interplay with the layout and architecture of the park creates a whole that is more amazing than the sum of its parts. Today, Vigeland Park is one of Oslo's most popular attractions, visited by over one million tourists each year.
