Down from Mount Hermon is the National Park of Nimrod Fortress, about which Mark Twain wrote "This must be the most glorious ruins mound of its kind in the world". It is one of the most impressive fortresses that survived from the Middle Ages. In this site one can tour around the fortress’ watch towers and underground water cisterns. Behind the fortress’ monumental gate is a huge lintel which features a large impressive inscription from 1275, the time of Baibars, the Mamluk Sultan, who conquered this country and extended this fortress and made it even more magnificent. In the archeological digs which took place here, among other finds a large stone with a tiger, Baibars’ symbol, etched on it was found. One of the attractions in this fortress is a hidden passageway built of huge stones which leaves the fortress through an opening that is well hidden on the outside. From every corner in the fortress one can see forested valleys and wonderful landscapes. At night, this fortress becomes enchanted with lights and one can have a tour here by the light of lanterns, the moon and the stars.
