The ancient city of Vaishali was considered one of the earliest examples of a republic. Here’s where the Buddha preached his last sermon before he attained his parinirvana. After renunciation, his spiritual training initiated here and here’s where he initiated the first woman disciple Gautami into his order.
Visit the Ashoka Pillar near the remains of a brick stupa where the last sermon was delivered, and pay respects at the Coronation Pond which contains the ashes of the Buddha.
