The Kesariya Stupa in Bihar, India, believed to have been built between 200 AD and 750 AD, is one of the tallest and largest Buddhist stupas in the world. The site holds historical significance as it is where Buddha spent his last days and donated his begging bowl. Parts of the statues at the site have been damaged over time, but recent excavations have discovered artifacts that shed light on the region's history. Plans are underway for systematic restoration and further exploration of the site.
