The keep is closed for the inner structure is no longer extant. However, because the repair crew was there they had opened an entrance into the base of the tower where they kept equipment. This entrance is of recent origin (about 150 years ago), for the original entrance is the opening at about mid-way up the side of the tower. The surface of the keep implies that the main structure with the living quarters was as high as 2/3 up the side of the keep, with the lower entrance actually going into the living area. The other entrance above may have been linked to a battlement that lined the top of the living quarters.
The keep is about 25 meters high and over 10 meters in diameter.
The base of the keep served as the cistern, and the photo at left shows the circular ceiling with the hole at the top to allow for a bucket to be lowered into the water. The photo indicates that this hole has been covered for some reason.
The left photo shows the remains of another tower with evidence of the stairs that were once built into its side.
It would seem that the water of the moat actually went beneath the castle, providing it with easy access to drinking water for normal day-to-day activities. The water in the cistern was stored in case the castle was besieged. Of course such an underground water passage could provide a weakness to the castle's defense, allowing a group of attackers to enter by stealth, infiltrate the inner ward and then open the gate to the rest of the attacking army lying in wait. Ancient and medieval history is repleat with examples of this very thing happening to fortified localities.
