This is Temple I made on the Xbox 360 version which has 18 doors which are all opened by one pull from a lever.

Inside there is a secret, hidden staircase which leads on to some puzzles one of which is a hidden door for which you need to place a Redstone Torch on the wall. There is a jumping puzzle too... and more!

This will eventually lead on to a secret chamber used for worshipping hell which then has a one way exit.

IMPORTANT:
If the jumping puzzle doesn't work the way to fix it is to go into the place where the redstone is (break blocks above netherrack) and replace the redstone torch on the block of netherrack in the circuit.

Additional Notes

This was a submission for TheGamingLemon's Top 5 structures: Redstone Creations.

I did this as a break from building Tronjheim.

I will also upload a video soon showing off the world.
