Standing at a height of 104 ft and with a diameter of 1,400 ft, the Kesaria stupa in Bihar is one of the highest in the world, twice the size of Sanchi stupa. In 1998, the Archaeological Survey of India had declared that it was the highest. Around 10 crore bricks were used to construct the seven-storey stupa, which has a strong significance in Buddhism. It is said that Lord Buddha spent a night here before his nirvana. Also, according to legends, after his enlightenment, as Lord Buddha travelled to Kushinagar, a large group of devotees followed him and refused to leave. When the crowd reached the then Kesaputta, Buddha urged them to return to their homes and after many attempts, they finally agreed. To console the group, Lord Buddha gave them his begging bowl. Emperor Ashoka built a stupa to commemorate that event.
