CLASS B. 



Fortresses on hill-tops with artificial defences, following the 

 natural line of the hill, 



e.g. — Mam Tor, Derbyshire.* 



Cadbury (near Wincanton), Somersetshire. 



Hambledon Hill, Dorsetshire. 



Hembury, Devonshire. 



Cissbury, Sussex. 



Badbury Rings, Dorsetshire.* 



Maiden Castle, Dorset. 



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

 slopes for protection, 



e.g. — Ambresbury Banks, Essex.* 

 Yarnbury, Wiltshire.* 

 The Auberys (Redborne), Herts. 

 Hunsbury, near Northampton.* 



The entrance ways to early hill-forts were frequently rendered 

 difficult of approach, sometimes circuitous as at Ardoch, dangerous 

 as at Comb Moss, or involved as at the east and west ends of 

 Maiden Castle.* Such entrance ways should be carefully noted.
