Ranmasu Uyana

Ranmasu Uyana is a park in Sri Lanka. It sits on approximately 40 acres (16 ha), and is a noted example of Sri Lankan garden architecture of the pre-Christian era. According to an inscription found in Vessagiriya, the water to the park was supplied by Tessa Wewa and then released to rice fields around Isurumuni Vihara.

Claims published on the internet and television documentaries that a carving within the park known as Sakwala Chakraya it was an interface or stargate "between humans and some intelligent species from outer space" have been called "absurd" by archeologists who suggest the carving could simply be an early world map.
