Jetavanaramaya was raised by King Mahasena in the 3rd century CE and was among the tallest structures of the ancient world. Legend has it that a part of the Buddha's sash is enshrined here. It has never been whitewashed, so where Ruwanweliseya is a gleaming white dome this one stands as raw red brick, and the two are worth seeing together for that contrast.
The Jetavanaramaya stupa comes with a fascinating historical significance which depicts the differences going on between the two sects of Buddhism- Theravada and Mahayana sects of Buddhism. Today, the stupa is no longer the tallest, but is one of the largest in the world, with an area of over five hectares and housing over 10,000 monks. The Jetavanaram stupa is a great way to experience the Buddhist culture in its purest form.
