This server is called Europa SMP and it runs Minecraft version 1.21.11.
The world is a custom 4000 by 5000 map that is based on Europe. So you can travel around and build on different places of the continent. It feels like a survival world where the land actually looks like a real region.
You have to send an application to join but they say it is easy. That makes the server feel more controlled and probably keeps out random trolls.
There is a simple voice chat plugin so you can talk to other players while you play. It makes exploring and building with people feel more like hanging out.
From what I can tell this is a completely new server so the map is fresh and not overcrowded.
