Within the palas one can find some excellent remains of the authentic castle. Right, some of the original stairs working up the levels of the palas. Note that the pieces extant in the wall are the same as those at the foot of the stairs.
Below, a view down the sanitation tower. Considering the size of the tower it is probable that the tower had several toilets at different levels, a unique feature that I do not recall seeing in any other castle. Of course, this may have posed a problem if you used one toilet above another level when a buddy was using the one below!
While there is clear evidence of mortar used for some restoration and reinforcement, the molding for the arched doorway is authentic. This would place such architecture as close to 800 years old.
Below, looking down into the inner ward from a portion of the palas.
Above, the stairs shown are probably authentic and not complete recreations.
Left, the center stairway (seen within above) that would lead up to the various levels of the palas. The main palas is beyond, with the beak quite obvious.
Left, a view from the keep looking down to the inner ward, with the area of the palas at the top.
Left, the palas (at left) with the gate going into the outer ward (at right).
Below, a composite of three photos taken from the keep, showing the stretch of the outer ward. Within the outer ward were several buildings, probably for general storage or stables for horses.
Above, a cistern showing authentic architecture with very little reconstruction or restoration. Note the notch to the left, the use for which I quite frankly am unsure of. The cistern's opening at the top was for dropping the bucket to draw water.
Right, one of the entrances in the palas. The iron gate is of course of fairly recent origin, but the stoop appears authentic, worn with virtually no restoration done.
