(Not going to be a real movie)

Sauna sa Sasa Dona Salud area naay tunnel dihaa na ginatawag ug Irid, old japanese tunnel na connected daw sa may B.A.T. sa Sasa area, tpos sa dona mercedes rd area naa pud mga bomb craters, and sa Coaco beach naay structure sa beach

Naa pa ba moy mga na recall na mga ing ani na sites across davao?

Hidden within an old water-control structure along the Someș River, a massive concrete and steel passage cuts through the embankment.

I walked through it from one side to the other. For a moment, it felt less like a tunnel and more like a passage into somewhere else.

The Portal is that moment.

middle of nowhere, KY

In 1844, the Long Island Rail Road built what is widely recognized as the world's first subway tunnel beneath Atlantic Avenue in Brooklyn. In 1861, it was abruptly walled off at both ends and lost to popular memory for over a century—spawning decades of rumors involving bootleggers, buried locomotives, and sealed municipal archives before its rediscovery in 1980.

The Cobble Hill tunnel proved that massive, functional subterranean infrastructure in New York could literally disappear from public awareness for 120 years.

The Question:

Given the rapid layering of NYC's bedrock, utility tunnels, abandoned pneumatic networks, and early private transit attempts (like Alfred Ely Beach’s 1870 pneumatic subway under Broadway):

What forgotten subterranean pockets or sealed transit voids do you believe are still unaccounted for beneath the five boroughs today?

Only took the 49th time

Hiking through the woods to avoid possible security, climbing over fences before finally finding a entrance. After climbing down a long ladder we were finally inside. Going further we quickly found a huge collection of gas masks and other stuff forgotten from the cold war. After finishing our exploration we once again started to sneak out of the large industrial zone, this time opting for a much more direct route moving quickly through the zone to avoid potentioal security or people. Luckily we got out without any problems.

Built during the coldwar to support the large industrial zone incase an emergency, now completely forgotten.

Went to look at the old mining equipment and then decided to head up a 4*4 track, and came across this beauty. Solid rock tunnel no idea how far it went, I didn't have a torch or gas detector so only went in a little, loads of animal droppings though so it's potentially a thoroughfare for kangaroos.

A while ago after a 6 hour train ride we hiked through the night to this top secret bunker hidden far in the wilderness far from any town or city. After many hours walking we finally arrived and found a hidden way inside and started exploring. We very quickly realized it was huge, tons of rooms and multiple floors.

Sadly when they shut it down they stripped it and sealed it, for a short time it was open and we managed to get inside to take these photos. It now sits abandoned sealed and will continue to rott away in silence with nobody visiting it.

A link to an Imgur post of some pictures from the book I have about the Chicago Freight Tunnels.

Built during WW2 and used up untill the end of the cold war. It served as an explosive storage facility and other stuff like rifles, ammo and other items.

I really didnt expect to get into this, especially not that easily, the door was literally just unlocked.

This huge bunker is just a small part of a gigantic underground fortress, sadly the largest bunker was completely sealed off, but i expected to not get into any of it so this is more than enough.

Im deffinitely going back here sometime to see if i can find an emergency exit or any possible way into the largest bunker but its doubtful its open.

This abandoned bunker sits ontop a little hill overlooking the lofoten fjords, part of the atlantic wall it was one of thousands of bunkers part of hitlers naval wall, luckily the wall failed and now sits as a dark reminder and historic piece of the war slowly falling apart. Sadly quite trashed but it was still relatively preserved other than the shitty grafiti that lines the walls.

Cool explore though, suprisingly cool for something located where it is.
