The great wall of Awwam (Arabic: سور أوام العظيم), also called the Awwam enclosure, is an ancient Sabaean wall that surrounds the gardens and the sacred sites of Awwam in Yemen.

[2] The earliest inscription found about the gardens' massive enclosure was by Mukarrib Yada`'il Dharih I in the 7th century BCE.

[3] 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.
