Without spoiling any quests or what was in the dungeon, I want people to tell me the name of their favorite dungeon and the general area it was in.

My favorite dungeon was Mzinchaleft, South West of Dawnstar.

DO NOT SPOIL ANYTHING ABOUT THE DUNGEON

I think my favorite so far was Valthume. Some hard bosses and got nice ebony shield and axe.

My favorite dungeon so far was probably the tomb where you get the Ghostblade, (can't remember the name or location), but it has the necromancer female who is raising Draugr to avenge the death of her once-imperial husband.
