Arnoun…Beaufort Castle or Qalaat el Shkif. 

Beaufort Castle stands on a rocky crest amidst enchanting countryside, not far from Mount Hebron and overlooking the Litani River in South Lebanon. Beaufort Castle, in Arabic Qalaat el-Shkif, is a mighty fortress standing on a strategic site on the roads of Tyre and the South. 

The view all around is panoramic and enough to take anyone's breath away. You will have a clear view all the way across the border of the country. 

The Crusaders took possession of it in 1139, and there are traces there of earlier Arab construction.
