And yet some thought was put into the interior design. The rooms are adorned with tiles more fitting of a home than the underground compound of a militant group. In the kitchen, the tiles are painted with bowls of eggs and gherkins, baskets of flowers and jars marked, in English, “flour,” “cookies,” and “cereals.”

"You can see in the kitchen; they even took time to make themselves feel at home here. The initial objective of this tunnel wasn’t to have the kidnapped here, this was a strategic tunnel, there is a toilet, there is a bathroom, there is a maintenance tunnel, the leaders spent time here,” Goldfuss claimed.

These aren't terrorist tunnels made for nefarious reasons, people lived down there...

And if you're wondering why people would.live in underground tunnels:

Emerging from the underground complex reveals the enormous destruction wrought by the Israeli military.

Goldfuss said a building once stood where CNN accessed the tunnel through a huge crater and other shafts spread like a spiderweb through the neighborhood. The devastation is immense – nothing was left of the original structure; its remnants having been bulldozed away to expose the tunnel entrance.

Similar devastation could be seen throughout the surrounding residential area. Most buildings had gaping holes instead of windows, giving them a dollhouse-like appearance. On several balconies, laundry hung out to dry was still flapping in the winter breeze. Books and personal items lay scattered around the rubble.

None of the buildings appeared to be liveable, and there was no one in sight.

Building those bomb shelters is entirely rational if you live in Gaza and are under constant threat of your country being flattened
