I didn’t actually get to step into this one. I went there early this morning, hoping to go by the place before work and explore quite freely. Regrettably, this was thoroughly thwarted by what was going on at the castle — namely, it is on private territory and access is granted between May and September only.
Nevertheless, from the one side facing the road I did as much exploring as one manages — which is some but not much at all, especially as of the four sides of this rectangular castle one manages to note only one! I would, however, still not consider this visit to have been wasted — I liked the layout and there’s plenty remaining there; plenty enough indeed to go and investigate this place in more detail at some point in the future.
Lastly, I did not end up getting much of a vibe of this place for the abovementioned obvious reasons. Still, there was something: perhaps this was the juxtaposition of the old and the new, with a minor road leading to West Caister bypassing the castle less than twenty feet from the moat and towers; perhaps this was something else. It could have been the elusive sense of the Norfolk ruins which so often accompanies these places in the slightly wet and rainy days as today was.
One of the better views I was left with is below:
