I think it would be very helpful to establish a list of the best Dungeons in the US, and Canada. My choices for the best Dungeons are Atlanta Dungeon The Den of Indomitus and Pandora's Box. I believe these Dungeons best exemplify the high standards submissives and fetishists are seeking in a commercial space. From Atlanta Dungeon's iconic Mistress Ultra Violet, to the legendary Mistress Porsche Lynn, and Pandora's box always hosting a cast of breathtaking Dommes. I have never been disappointed by these great house's of BDSM.

Quite a few places mentioned in this thread from last year.

From what I've read since then I think I'd also add Mistress Victoria Rage of Seattle and Miss Grey of San Francisco . Their spaces look pretty impressive too.

I think the original post was about houses with multiple Dommes. But since you expanded it to include dungeons run by individual Dommes, Irene Boss's Compound in Pittsburgh qualifies.

I've been in many of the top commercial dungeons in the U.S. and Europe (including all three in the original post) and Irene's space equals or exceeds them all.

Disney Land for kinky adults.

In rereading the original post I think you are probably right. I guess I automatically equate "dungeon" with play space or BDSM studio.

I've been to Pandora's years ago and it is a great dungeon. In my travels I've never been to the Atlanta Dungeon, so shame on me. The big surprise on this list is The Den of Indomitus and Porsche Lynn. I haven't heard about that dungeon or the legendary Porsche Lynn in years. Glad to see both are still around. And I was very surprised and happy to see that Goddess Athena, formerly based in Philly and used to visit NYC, while now a blonde is still in the scene. I served her a couple of times in Manhattan in the early part of this century, and she was, probably still is, a force of nature. Thanks for the post.

I think it's OK.

One of the purposes of this board is to share intelligence. You and I just gave some folks who don't know about these places some very good advice.

Yes, there certainly are some impressive spaces here although I've always found it interesting that the US has never seemed to develop more extensive facilities like Europe. (thinking of places like OWK, Studio Avalon, Warsaw Prison etc)

I've always been fascinated by the idea of being checked in to such a place for an extended period of training and conditioning.

edit
The old mill in Mass used by Goddess Nemesis also looks like an amazing space.
