Favorite ruins/abandoned areas in Star Wars?

Throughout your reading or venturing into the Star Wars EU, what are some of the areas you thought were mysterious or unique? What planet or historical site would you spend a great deal of time at, or what areas really stuck out to you as somewhere you'd go or stay at?

One of the weirdest/most mysterious places is Sinkhole Station to me, it creeped me out while I was reading Abyss.

Ossus. Should've been used instead of Tython.

The legends continuity

Katar. I've always wondered if that place was a graveyard like Natheema or a echo like Malachor. Also, Malachor lol.

I doubt its like Malachor but I'd like to know if its like Natemha or not.

Ilium Korriban. Almas some locations in the unknowed regions..

I bet the ruins of the imperial palace on dromund kaas around the time of the galactic empire would be pretty cool.
