In the flat region of Eastern Uganda, some oddities happen, like very circumscribed areas where giant boulders and other rocks seem to have landed there, as if they had fallen from the sky. In one of such areas, Nyero, even odder oddities can be seen. It appears an ancient civilisation (it is still unclear who and when) had taken refuge in this area and left a mark on some of the rocks. Three main sites can be visited easily (but there are more), very poetically named Nyero 1, 2, and 3. If you know anything about primitive art, you will be able to rave about the painters' skill and ingenuity, but even if you're just the average uncultured traveller, you will no doubt appreciate the great geometrical forms of the paintings and the beauty of the surrounding landscape. And next time you see a 1000 Ugandan shillings bill, you'll be able to boast: I have seen the original.
