Niha has been inhabited since the Roman times. The most famous monument in Niha is the cave fortress (Cave of Tyron). This cave was used by the Crusaders and the Mamluks to control the vital road linking Saïda to the Bekaa valley (it also became famous as the refuge of Emir Fakhreddine).
The shrine of Nabi Ayoub is built on a summit overlooking the village of Niha where the prophet Job is believed to be buried. Pilgrims frequently visit this site. Niha is rich in old springs such as Ain el Qataa, Nabeh Niha, and the very old Ain el Halqoum.
It also has old traditional houses, two ancient churches (Saint Joseph and Saint Georges), two old bridges (El Jisr el Tahtani and Jisr Tareeq el Nahr), and an old water mill. Niha has a well run private guesthouse and an information center managed by the Shouf Biosphere Reserve
