The great wall of Awwam (), also called the Awwam enclosure, is an ancient Sabaean wall that surrounds the gardens and the sacred sites of Awwam in Yemen.
The earliest inscription found about the gardens' massive enclosure was by Mukarrib Yada`'il Dharih I in the 7th century BCE. The enclosure is defined by a massive oval shaped wall, measuring approximately 757 m long and 13 m high; however the original height length can't be determined for certain.
