The Blue Hole (Maltese: Iż-Żerqa) is a round, flooded shaft in the rock shelf at Dwejra, Gozo, about 70 m south of the Azure Window. Under the water, an arch joins it to the open sea. It is one of the best-known dive sites of the Maltese islands. In Malta in Minecraft you can dive the arch and swim out to sea.
How it differs from vanilla
- Its own biome (
maltamc:zerqa_blue_holeon the F3 screen): darker blue water than the sea around it, a gravel floor and bare rock walls, with no seagrass. - A flooded shaft joined to the sea by an underwater arch. Minecraft never makes one on its own. Natural caves near the arch are filled in, so its walls are solid rock.
What to see
| What | Size in the world |
|---|---|
| Shaft | about 15 m across, open to the sky |
| Depth of the shaft | about 15 m, gravel floor |
| Underwater arch | about 9 m wide, its roof about 6 m below the surface, its floor about 15 m down |
| Length of the arch | about 30 m, from the shaft west to the open sea |
| Open sea outside | about 15–23 m deep, from the 2012 seabed survey |
- Look down from the rim to see the dark blue water against the pale rock shelf.
- Dive the arch: swim down to about 6 m on the west side of the shaft and through the arch to the open sea. It is dark inside, and the far end shows as a blue glow.
