Promontory forts always strike me as desperate, desolate places and this reinforces that feeling. Did the people who had to retreat here know peace? Or were they always on edge (literally)?
Ryaner, interesting thoughts. Might depend on the degree to which they were genuinely inhabited, or maybe stock pens in some cases. I went to an inland "promontory" fort yesterday, just off the Black Mountains. The internal slope was extreme to say the least - the rampart was almost more of an obstacle from inside the enclosure than out (although the ditch is external).
I'm absolutely fascinated by them, and we've a wealth of them here in Waterford.. Island Hubbock is particularly spectacular ( http://binged.it/TNdQDZ )
