The Castle — Its Architectural Features. ii 



part of the overlapping stones of the roof could be 

 found, these were put in on the south-west corner, 

 and the remainder of the roof was carefully made 

 watertight with cement. 



The parapet round the roof is brought up flush 

 with the face of the walls, and most of the embrasures 

 can still be traced. The roof was doubtless con- 

 structed flat for the convenience of working military 

 engines. The total height of the keep from the 

 top of the rock is about seventy feet, and to the base 

 about ninety feet. The additions which have been 

 made at various times have considerably altered the 

 aspect and internal arrangements of the castle, especi- 

 ally with regard to the entrance. In the first instance, 

 a great curtain wall was erected, the keep itself form- 

 ing a part on the south, with angle towers, and 

 enclosing a courtyard. The space within the outer 

 walls averages 122 feet from east to west by 80 feet 

 from north to south. Later, and at various times, 

 within this courtyard, buildings have been added 

 against the curtain walls on the east, west, and south 

 sides. The entrance gateway was in the north curtain.
