As many arid regions of the world Nambia has had a rich crop of meteorite finds. Apart from the Gibeon Meteorite Shower, which is the most extensive known on Earth, it also hosts the Hoba Meteorite (largest single meteorite), as well as the Roter Kamm, an impressive impact structure, which however has yielded no remains of the projectile that created it. While the removal of meteorites from their site of impact is prohibited by law, some of the largest fragments of the Gibeon Meteorite Shower can be seen at a permanent display in Windhoek's Post Street Mall and at the National Earth Science Museum. And the Visitor Centre on Farm Hoba west of Grootfontein was established by the National Monuments Council to provide interesting information about the famous relic from outer space.
