The Chakhil-i-Ghoundi Stupa, also code-named "Stupa C1", is a small limestone stupa from the monastery, at the archeological site of Hadda in eastern Afghanistan. Most of the remains of the stupa were gathered in 1928 by the archeological mission of Frenchman Jules Barthoux of the French Archaeological Delegation in Afghanistan, and have been preserved and reconstituted through a collaboration with the Tokyo National Museum. They are today on display at the Musée Guimet in Paris. It is usually dated to the 2nd-3rd century CE.
