This engraving was published in The Illustrated Christian Weekly 26 Aug 1882. The text explains that the citadel was built by Saladin in 1170 AD. The mosque, crowning the highest point, was built by Mohamed Ali ‘the founder of the present family of Khedives, [who] on March 1, 1811, horrified the world. Having invited the Memlook nobles into his council, at a signal he massacred them all, save one, who leaped his horse over the parapet.’
