CLASSIFICATION. 



The following classification of defensive works is recommended by 

 the Committee : — 



A. Fortresses partly inaccessible, by reason of precipices, 



cliffs, or water, additionally defended by artificial works, 

 usually known as promontory fortresses. 



B. Fortresses on hill-tops with artificial defences, >//tfr<;wz^ the 



natural line of the hill. 

 Or, though usually on high ground, less dependent on 

 natural slopes for protection. 



c. Rectangular or other simple enclosures, including forts and 

 towns of the Romano-British period. 



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



fosse. 



E. Fortified mounts, either artificial or partly natural, with 



traces of an attached court or bailey, or of two or more 

 such courts. 



F. Homestead moats, such as abound in some lowland 



districts, consisting of simple enclosures formed into 

 artificial islands by water moats. 



G. Enclosures, mostly rectangular, partaking of the form 



of F, but protected by stronger defensive works, ram- 

 parted and fossed, and in some instances provided with 

 outworks. 



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



X. Defensive works which fall under none of these headings. 



Illustrations of typical forms of earthworks were published in the 

 " Scheme for recording defensive earthworks and fortified enclosures," 

 and in the Appendix. These will be sent on application to the 

 Honorary Secretary.
