Jaya Sri Maha Bodhi
This sacred fig tree surrounded by temple walls is the oldest living tree planted by humans with a known planting date. That date: 249 B.C. What really catapults the Jaya Sri Maha Bodhi tree into super-stardom, though, is its sacred history. It's believed by many to be from a cutting off the Sri Maha Bodhi tree in India, under which Buddha reached enlightenment. Today, Buddhist pilgrims and others from around the world make their way to the Mahamewna Gardens in Anuradhapura, Sri Lanka, to pay homage to this living spiritual symbol.
