The world's largest monument is this 563ft-tall work-in-progress (with a lot of work to go). When finished it will depict the Sioux leader astride his horse, pointing to the horizon saying, 'My lands are where my dead lie buried.'

No one is predicting when the sculpture will be complete (the face was dedicated in 1998). Although you can see the mountain in the distance, you need to pay another $4 for a van ride to get close.

Never photographed or persuaded to sign a meaningless treaty, Crazy Horse was chosen for a monument that Lakota Sioux elders hoped would balance the presidential focus of Mt Rushmore. In 1948 a Boston-born sculptor, the indefatigable Korczak Ziolkowski, started blasting granite. His family have continued the work since his death in 1982. (It should be noted that many Native Americans oppose the monument as a desecration of sacred land.)

The visitor center complex includes a small Native American museum, gift shops, cafes of limited merit, and a fragment of Ziolkowski's studio. A laser-light show plays off the monument on summer evenings.
