Ruined castle on the road to Bantry. There’s an old stone bridge about an arm’s span wide leading up to this place, and we watched cars navigate the bridge with the nervous horror of people certain they’re about to witness utter doom AT ANY MOMENT. We didn’t, but the I’m sure it’s still waiting to happen.
The castle, though, was really worth stopping at. You can’t get into the actual ruins, but we were able to go all around them. As you can see, the river running by is in quite the little ravine, making the place quite defendable. (What, don’t normal people consider this when looking at ruins?) Anyway, it’s another good reason to risk the road to Bantry. :)
