There's one four-way stop I pass regularly in Ireland [0].

I suspect there isn't enough room for a roundabout, and we also don't tend to construct roundabouts on hills (I'm not sure why they're any worse than other junctions there). There's a steep gradient going uphill from South to North.

Normally it would be a two way stop, and I sometimes wonder why that wasn't chosen here. Likely because visibility is bad (trees, walls, curves - it's worse than it looks in the satellite image) and cars coming from the east and west can't completely tell that it's safe to enter the junction.

A four-way stop would be confusing for me, those don't exist in my country as far as I'm aware. I was also thought that a stop or yield sign means I'm on the side road and the other road implicitly has priority.

The concept of priority and side road was too complex for North Americans. Yield signs virtually don't exist here.

It can get complex for us here as well, one example is when the priority road doesn't go straight through the intersection, eg. L-shaped main road, and then the other two have a stop and a yield sing. A lot of people where I live wrongly think that the yield has priority over the stop sign, it's a widespread misconception (I'd say more people believe it than not). In reality the priority to the right rule applies between side roads and the only difference between yield & stop is that the stop sign requires you to actually stop the vehicle. And then there are plenty of T intersections in smaller towns and villages where people assume the road going straight is the main road, even though there aren't signs and the priority to right would apply. I guess drivers mostly rely on habits and intuition.
