Anuradhapura is a UNESCO World Heritage Site of religious and archaeological significance. The sacred city is home to the Sri Maha Bodhi Tree, grown from a cutting of the original Bodhi tree under which the Buddha attained enlightenment, making it one of the holiest sites in the entire Buddhist world. Enormous ancient stupas, including the Ruwanweliseya and the Jetavanaramaya, once one of the tallest structures on Earth, rise above the surrounding landscape in breathtaking scale.
