Bat's Castle is on the hill behind (ie west of) Dunster's charming medieval stone castle, itself beside Dunster's modern town centre. Bat's Castle is probably about a 10 - 15 minutes walk up the hill towards this ancient hill-fort (& also some Cromwellian artillery ramparts - from where Parliamentary forces bombarded Dunster's stone castle & town centre in the 1640s English civil war). Bat's Castle is circular with rough stone walls, with some of its layout suggesting parts of it might have been used to corral animals in during both peace & war.
Slightly below it & to its west is a hillside site which appears to be an ancient farm with a low embankment around it. The higher part of the enclosure suggests the residential area. The lower western part is where animals would probably have been kept - deliberately lower so that their slurry flowed away from the humans who would presumably have been living slightly higher up the hillside than the animals.
Surprisingly, Bat's Castle has been associated by some (not by all - some tourist officials in Dunster were unaware of this until I showed them a booklet making this claim) with the legendary King Arthur in his youth. The suggestion is that Bat's Castle was his first command, & sallying out from here he fought & conquered a local pirate/warlord who was much troubling the local people at the time. When? Probably around 470 - 480 AD, if this story is to be relied on.
