Crac de Masyaf, Syria

We were taken to Crac de Masyaf on the day trip to Crac des Chevalier.
Had no idea what this was about but found some interesting history about this.
The word 'assassin' derived from the Arabic word 'Hashshashin' which means the shia Muslim people who thrived here under Rashid al-Din Sinan ("the Old Man of the Mountain")'s control.
The Ismails 'Hashshashins' were believed to have had hashishi before going into wars so the word 'Hashshashin' means 'people who do hashishis'. They were Muslims but sometimes fought for crusaders when it was suitable, so they became well known to the Europeans then.
