Buddhist Stupa of Many Doors also known as the Stupa of Many Gates. After reaching enlightenment, the Buddha taught his first students in a deer-park near Sarnath. The series of doors on each side of the steps represent the first teachings: the Four Noble Truths, the Six Pāramitās, the Noble Eightfold Path and the Twelve Nidānas.

Each stupa has an openable space that can be filled with proper substances by traditional way.
