Acre Citadel

King Richard's Citadel was a huge fortress in the southern rich district of Acre and also the main residence of Richard I of England.

The citadel is secured by huge walls and operates like a small town within itself. It also contains the quarters of William of Montferrat, a Templar, who governed the area when Richard was absent fighting the Saracens.

In 1191, the Assassin Altaïr Ibn-La'Ahad infiltrated the heavily guarded fortress in order to assassinate William.

A couple of years later, Altaïr and Maria Thorpe met atop of the citadel's tower where he impregnated her.
