Ethiopia’s historic route begins with a glance at the enticing remains of Yeha-the center of the earliest civilization in northern Ethiopia .the journey takes you on rough tracks through the dramatic highland scenery ending in a serene agricultural hamlet. Yeha, which lies to the northeast of Axum, is the site of the famous Temple of the Moon, Ethiopia's oldest standing structure.

It is generally agreed the Temple of the Moon was built during the time of the D’mt Kingdom in the 8th and 7th centuries BC. The D'mt Kingdom preceded the Axumite Kingdom. When and how the transition from the D'mt Kingdom to the Axumite Kingdom occurred has not yet been determined. The oldest standing structure in Ethiopia is located in Yeha: the Great Temple. This is a tower built in the Sabaean style, and dated through comparison with dated structures in South Arabia to around 700 BC; although no radiocarbon dating testing has been performed on samples from Yeha, this date for the Great Tower is supported by local inscriptions. David Phillipson attributes its "excellent preservation" to two factors, "the care with which its original builders ensured a level foundation, firmly placed on the uneven bedrock; and to its rededication -- perhaps as early as the sixth century AD -- for use as a Christian church. Two other archeological sites at Yeha include Grat Beal Gebri, a ruined complex distinguished by a portico 10 meters wide and two sets of square pillars, and a graveyard containing several rock-hewn shaft tombs first investigated in the early 1960s. One authority has speculated that one of these tombs contained a royal burial, while another believes the ancient residential area was likely one kilometer to the east of the modern village.

Yeha is also the location of an Ethiopian Orthodox monastery, founded according to tradition by Abba Aftse, one of the Nine Saints. In his account of Ethiopia, Francisco Álvares mentions visiting this town in 1520 (which he called "Abbafaçem"), and provides a description of the ancient tower, the monastery, and the local church. This church was either the rededicated Great Temple, or a now destroyed building which the Deutsche Aksum-Expedition described in the early 20th century. (The current structure, which exhibits Aksumite architectural features, was built between 1948 and 1949.

Yeha has also been the site of a number of archaeological excavations, beginning in 1952 by the Ethiopian Institute of Archeology. Although interrupted during the Derg regime, excavations were resumed in 1993 by a French archaeological team.
