The Fortress of Niha (also called Cave of Tyron in Frankish sources and Chquif Tayroun in Arabic sources) is an ancient fortress in Lebanon, first mentioned in historical records in 975 AD.

It is located in the municipality of Niha Chouf in Lebanon, and is today visited as cultural heritage in the Shouf Cedar Nature Reserve.

Control over the fortress alternated between the Crusaders and local Muslims until its destruction in 1261.

In 1585, the Emir Qorqomaz Maan probably took refuge in it briefly before his death.

[1] Shaped like a cave over a hundred meters deep, the fortress features chambers and rooms which were excavated in order to shelter soldiers and as depots for domestic work.
