The castle had a complex hydraulic architecture to ensure a supply of water that was not dependent on outside sources. This was a key factor, particularly at times of war when it was not possible to leave the fortress. Water was needed for human and animal consumption and also in the event of a fire, which was one of the commonest ways of bringing castles down.
We have both direct and indirect evidence of the existence of other buildings such as horse stables, which were necessary for husbandry and war. Apparently, the stables were to one side of the bailey, between the keep and the gates of the castle.
In this area there must also have been the barracks , housing the soldiers stationed at the castle and the reinforcements in times of conflict. This area would include a kitchen and a canteen although soldiers of the time eating did not require much formality. Most likely, there would have been an oven there as well.
