Talk:Nether Fortress/@comment-26991840-20150916150733/@comment-7196-20160705183844

Not sure if it's accurate on MCPE, but Gamepedia says this:

"Nether fortresses tend to cluster together in strips that run along the Z-axis (north and south). Players who travel along the X-axis (east or west) will have the best chances of finding one; those who travel north or south may travel for hundreds or thousands of blocks before discovering a fortress.

Nether fortresses may be generated in inconvenient places, where half of or even the majority of the fortress is buried in netherrack. The interior will not be filled, however; all hallways and passages will be clear except for open walkways and bridges."
