Barentu is a town in north-western Eritrea, lying south of Agordat, and is the capital of Gash-Barka Region. The town is integrated with different types of tribes: Kunama, Nara, Tigre and Tigrinya being the most dominant.
It was mainly inhabited by the Nilotic Kunama people and Nara people in the past. The Nara people leader Shekaray Agaba was the first to build the town Umba Arenku which it means the white water. It is located in the Gash-Barka Zone of Eritrea. Barentu is the largest town in the Gash-Barka Zone in Eritrea, lying west of Asmara. It is the capital of the Gash-Barka and home of the Nara and Kunama Ethnic groups.
The town has typically been a center of mining and agricultural activities for the area. During the Eritrean War of Independence the town was besieged. As part of the Eritrean-Ethiopian War of 1998-2000, the then flourishing town suffered major damage but has since undergone reconstruction. Thus it now attracts settlers from all parts of the country especially from the Gash area and the Eritrean highlands. Owing to this factor the town has expanded rapidly in the last decade. This rapid expansion is also partly attributed to the Eritrean returnees from Sudan who established their home in the town after years of migration spent in Sudan.
Barentu is the administrative center of Barentu Subregion; has basic electricity services, a hospital and a clinic. The town consists of 3 administrative quarters or zobas (as they are called in tigrigna) namely zoba Fthi [ፍትሒ], Selam [ሰላም] and Biara [ቢያራ].
