The chedi
The chedi or stupa is likely the oldest structure of the temple. Although it is not known exactly when it was built, it was enlarge and rebuilt in 1449. It was enlarged again at the end of the 15th century to its current height of about 45 meters. The chedi is covered with bronze and copper sheets that have weathered over the centuries and changed its color. The structure enshrines a hair relic of the Buddha, that was donated by the Buddha when he visited the site some 2,500 years ago. The chedi is not open to the public.
