CLASSIFICATION. 



The following classification of defensive works is recommended by the 

 Committee : 



A. Fortresses partly inaccessible by reason of precipices, cliffs, or 



water, defended in part only by artificial works. 



B. Fortresses on hill-tops with artificial defences, following the 



natural line of the hill. 



Or, though usually on high ground, less dependent on natural 

 slopes for protection. 



C. Rectangular or other enclosures of simple plan (including forts 



and towns of the Romano-British period). 



D. Forts consisting only of a mount with encircling ditch or 



fosse. 



E. Fortified mounts, wholly or partly artificial, with remains of 



an attached court or bailey, or showing two or more such 

 courts. 



F. Homestead moats, consisting of simple or compound enclosures 



formed into artificial islands by water moats. 



G. Enclosures, mostly rectangular, partaking of the form of F, 



but protected by stronger defensive works, ramparted and 

 fossed, and in some instances provided with outworks. 



H. Ancient village sites protected by walls, ramparts or fosses. 



x. Defensive or other works which fall under none of the above 

 heading's.
