My latest completed white dwarven fortress.
With a huge dug out halls in the mountain.
Completely dug out by hand in vanilla survival without using cheats/mods.
on our vanilla survival server as usual :)

Don't have a timelapse of this since this construction began over a year ago.
It used to be a new map generate error with a hard edge mountain cut into sea level.
So first there was a simple bridge.
Later the 2 most right towers where build on the bridge and the last week I've a the rest to it. and made the mountain look a little better.
I've build all the rest and dug out the halls in just a few days. :)
