Haḍḍa (Pashto: هډه) is a Greco-Buddhist archeological site located ten kilometers south of the city of Jalalabad, in the Nangarhar Province of eastern Afghanistan.

[1] The style of many of the works at Hadda is highly Hellenistic, and can be compared to sculptures found at the Temple of Apollo in Bassae, Greece.

The former - if not a fossilized form - would have given rise to a Haḍḍ in the subsequent vernaculars of northern India (and in the Old Indic loans in modern Pashto).

They are part of the long-lost canon of the Sarvastivadin Sect that dominated Gandhara and was instrumental in Buddhism's spread into central and east Asia via the Silk Road.

[6] A sculptural group excavated at the Hadda site of Tapa-i-Shotor represents Buddha surrounded by perfectly Hellenistic Herakles and Tyche holding a cornucopia.

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.

The decoration of the stupa provides an interesting case of Greco-Buddhist art, combining Hellenistic and Indian artistic elements.

[12] One of its most famous artifact is an attendant to the Buddha who display manifest Hellenistic styles, the "Genie au Fleur", today in Paris at the Guimet Museum.

It was excavated in 1926–27 by an expedition led by Jules Barthoux as part of the French Archaeological Delegation to Afghanistan.
