I started making this cathedral maybe, a month ago? I'm not entirelly sure, but I've been adding onto it bit by bit. It's taking a while because some days I can build tons, others I can't think of anything.
so far most of the exterior is done, all gothic/nether style. The interior is empty for now.

Additional Notes

Thanks goes out to kipper1998 for help on the dome and to Burnt Valentine for ideas on the walls and the wall/paths around it! :D
