Here is a gigantic temple with different things like several kinds of a maze, a jump 'n' run and a private house for the owner of this facility.

You can see my temple here, which I built on the [url=http://http://web.diacraft.org/]Diacraft server[/url]. Inside are several mazes and a jump'n run on top. The house has a panoramic view over the jump'n run due to blockades underneath. 
You can of course add in other things like puzzles, traps, etc.

Here are some pictures.

from the labyrinth the picture is difficult because you can see only one corridor and a few intersections. Therefore there is no picture here
