Kesariya Buddha Stupa is an ancient Buddhist monument located in the East Champaran district of Bihar. It is believed to be one of the tallest Buddhist stupas in the world, reflecting the grandeur of early Buddhist architecture. The stupa is associated with Lord Buddha’s final journey, where he is said to have stopped and offered his alms bowl to the people of Vaishali. Archaeological evidence suggests multiple phases of construction, mainly during the Mauryan and later periods. The massive circular structure is built with layered bricks and shows advanced engineering of its time. The surrounding area has a calm rural landscape that adds to its spiritual aura. The site is important for understanding the spread of Buddhism in eastern India. Kesariya Buddha Stupa continues to attract pilgrims, historians, and heritage enthusiasts.
