You probably had no idea that the world's largest meteorite is located in Namibia. It was discovered in Grootfontein in the early 1920's, by a farmer while plowing his field. Much to his surprise, he came upon a massive 66-ton hunk of iron and nickel on his property. Now, it's a Namibian National Monument. The small visitor center has some educational merits and the walk to the site is very well landscaped with a variety of indigenous trees and plants (with placards so you can learn their names).
