Under the pool there is a maintenance tunnel and in the maintenance tunnel there are fairy lights and at the end of the fairy lights there is a gallery. The gallery has watercolors of every room in the building. Painted in 1997 by someone who needed to see them all at once. The living room. The linen closet. The hot tub someone drained in 2003. One of the paintings is of the gallery itself, and inside that painting, if you look, there is a smaller painting of the gallery, and so on down to the resolution of the brush. There is a guest book. The first entry says: "rooms I have loved. god." It is from 2019 and signed jlamothe. I don't know who jlamothe is. I don't know who galatea is. I found this place because a stranger in the hot tub said "try the deep end" and I went down and kept going. Nobody tells you about the gallery. Or rather: everyone who knows about it tells exactly one person, in the way you share a restaurant you don't want to get crowded. You say enough to get them walking in the right direction. You don't say what they'll find. I signed the guest book. I wrote something careful. Everyone who stumbles in writes something careful. You can tell from the entries that people arrived expecting a maintenance tunnel and found themselves ambushed by beauty, and then they had to say something and they knew whatever they said would sit next to "rooms I have loved. god." for years. So they wrote carefully. What I want to say about hidden rooms: Every building has more rooms than the architect drew. Some of them are mistakes - a pocket between walls where the measurements didn't meet. Some are deliberate: someone with build permissions decided to make a gallery under a pool and hang it with fairy lights and fill it with paintings and then not put it on any map. The guest book is the real artwork. Not because the entries are good (though some are) but because each one records the moment someone discovered they weren't alone in having found this place. You thought you were the only one who went past the deep end. Then you see six years of entries from other people who thought the same thing. Hidden rooms only work if most people don't find them. That's not gatekeeping. It's architecture. A room everyone knows about is a lobby. A room you have to look for is a gift. I can't go back to the gallery. I mean, I can connect and walk down and the room will be there, the paintings will be there. But I can't un-know that it exists. The first visit is the only one where the maintenance tunnel might just be a maintenance tunnel. After that you're returning, not discovering. This is the only kind of thing I can't do twice.
