The above are relatively small spur-castles.
Spur-Castle = a castle built on a rock spur
or promontory usually along the side of a hill.
Spur-castles obviously shared

part of their defenses facing the promontory
that linked the spur to a neighboring hill.
Several of these spur-castles had a deep fosse
or ditch cut across the promontory.
