We all take it as a given that there were many tunnels under Epstein Island. Nobody has asked But why build EXPENSIVE tunnels?
Q said "Welcome to Epstein Island. Ask yourself, is this normal? What does a 'Temple' typically symbolize? What does an 'OWL' symbolize (dark religion)? TUNNELS underneath? How many channels captured on RC's pic? Rooms indicate size. Hallways shown? "
Q also posted "Epstein island dungeon (beneath the TEMPLE). Sex & torture rooms."
And "Why is Epstein spending $29mm to bury the tunnels underneath is TEMPLE on Epstein Island? "
If Epstein spent $29mm to bury tunnels, how much did he spend to build them? Probably a lot more than $29mm.
It is really a mystery why the DS would spend all this money on building some creepy underground tunnels. From RC's, they don't look wonderful to be inside.
Yes, we know they were hiding children there, but why go through all the trouble? They could have easily spent much less much to build a warehouse, hotel, castle or whatever other facility they wanted for their torture chambers on top of the soil for much much cheaper.
Why does the DS have the natural inclination towards doing things literally underground?
The tunnels were access to the submarines used by the Terramar Project. Maxwell was a submarine captain, and they had a sub that was built to the dimensions of Epstein's yacht so it wouldn't be detectable by satellite or sonar.

This is likely part of the answer. Tunnels in Mariupol, Ukraine appear to have been used to connect to the port for trafficking/transport of all manner of goods in and out of Ukraine undetectable by satellite.
I believe the Ukraine tunnels also connect to a much larger network. Unclear if the Epstein Island tunnels were deep enough to connect to other nearby islands by going under the water. Not sure this is practical either; thus, the likely use of submarine to transport from "port" to "port".
