How to find the tower and WHERE AM I?! XD

Hello guy,
I currently have a godtier run going on. Believe me, it is XD I can kill everything, got 1500+hp and more blood+vampirism.
I also have like 25 perks+ its crazy.

So I wanted to go to the tower for the first time and cant find it. I killed the boss, didnt take the portal, dug back to the temple and went to the far left (I saw in a video that there is a big room with the portal). But I couldnt find it at all. I used black holes and found a HUGE snowy biome where you couldnt move freely without digging and it had no wands or hearts, just some enemies.
Somewhere adjectent to it I then found a place called snowy vault. I almost fully cleared it and saved the game.

Can somehow show me a map and point at where I am and how I can find the tower?

Thanks for the long text and thanks in advance! :)

Keep in mind the tower can still kill you fairly easily. It has a bunch of unkillable enemies in it too.

You can find it by moving to the far left of the Temple of the Arts(lowest layer). Here you'll find a "???" room with a floating square filled with lava, destroying the square will reveal a portal to the tower.
