This is the portal chamber that I use on my server. It has total of 13 portals in it plus two portals to get back into your main world. It is possible to add even more portals in the dome and customizing it is really easy. The structure is very large and it has very impressive walls and roof. "Easy to customize - Large and impressive"

Total of 4.5 million blocks: 3.7 million air blocks, 70k stone blocks, 63k stone bricks, 150k water blocks, 2k iron and gold blocks, 1.1k obsidian, 400 diamond, 2.7k emerald blocks and much more. :)

This portal chamber has been divided to 4 parts: You teleport in the center of the chamber. Paths lead to PvP, Event/Contest, Biome and Creative portal islands.

Themed portals: The structure has portals for each biome. Taiga, Jungle, Desert, Swamp and Mushroom! To make the system easy and simple, each portal has been built so they match the biome they will teleport you in to! We also have Nether, end and second survival world portal built in, each of them themed correctly ofcourse.

Awesome use of light: As you first see the structure, you will notice how there is holes on the roof, they create nice figures on the water, making it look impressive aswell.

If you download this structure, please click the diamond first. Thats the only reward I want for this. Thank you :)
