The Cathedral of Pain, also known as Asylum Station 3 or the Schism Chambers, serves as a vital area in the Asylum located in Deadside. Like the rest of the Asylum, it was designed by Jack the Ripper.
The upper part of the level is where the main part of the cathedral is located. Distinguished by its Gothic-style achitecture, it features five altars and shrines dedicated to each member of "The Five". Each altar also includes a corpse of that respective member.
On the initial visit, only 2 of the conduits are open. The other three have to be opened via retractors. 2 Dark Souls can be found here. There is also a large hole in the central area (PC, Dreamcast and Remastered versions only) that leads to the lower area. A small theatre-like area can also be found on the upper floor (PC, Dreamcast and Remastered versions only).
The lower area is filled with hot coals and moving machinery. Unless Shadow Man has visited the Temple of Prophecy, this area cannot be explored.
This area, along with the rest of the Asylum, was destroyed upon Legion's defeat at the hands of Shadow Man.
