The Kesaria Stupa's construction is attributed to various periods, with some scholars linking it to the Mauryan era (3rd century BCE) and others to the Gupta period (4th-7th century CE). It is believed that the stupa was built to commemorate a significant event in Buddha's life, possibly his last sermon or his donation of a begging bowl. Over the centuries, the stupa underwent several phases of construction and expansion, resulting in its present-day tiered structure. Despite numerous excavations and discoveries, its full history remains a subject of ongoing research. The stupa's existence highlights the deep-rooted Buddhist influence in this region of India.
