Hollowfind
A tiny round wooden door tucked into the roots of a big tree, with a lantern, a pebble path and a little chair.
St. Louis · coming soon

There's a tiny door at the bottom of that tree.

Hollowfind is a map of the fairy houses tucked into tree roots, and of the tiny handmade pieces people find inside them.

How it works

Find a house. Visit. Take something small home.

Map

Find fairy houses near you

Houses in parks and on trails get an exact pin. Houses on someone's property show as a rough area, so nobody ends up at a front door.

Houses

Visit, and see what's changed

Tap “I visited!”, add a photo, and follow each house's history: a new pebble path, a lantern, a fresh patch of moss.

Every piece carries its own code. Scan it to make it yours and see every house and town it has passed through.

Drops

Pop-up hunts in small St. Louis parks

A drop is a Saturday-afternoon treasure hunt, about the size of an Easter egg hunt. Watch the map, head over, and see what's tucked into the roots.

  1. We hide a handful of piecesEach one sits at the base of a tree in a small neighborhood park.
  2. Spots open on the mapEvery spot has its own time window, so the hunt moves through the afternoon.
  3. Take one homeScan it right there or at the kitchen table that night. Scanning is up to you.
  4. Everything's gone by sunsetWe pick up whatever's left. Nothing stays out overnight.

Pieces

One new handmade piece a week

Every design starts on a workbench: carved, sculpted and painted by hand. Then it's scanned and 3D-printed in a tough plastic that holds up outdoors, and each copy gets its own code, either a small QR sticker or an NFC tag hidden inside.

1new design every week

Small parts. Pieces are not for children under 3.

Kind by design

Built for families, and for the trees

Homes stay private

A fairy house in someone's yard or condo courtyard shows as an area on the map, never a pin.

Pieces don't track you

A piece is logged at a fairy house or at town level. Your exact location is never stored.

Every photo is reviewed

Photos are checked by a person before anyone else sees them. No faces, house numbers or street signs.

Leave no trace

At public houses, look and take photos. Pieces from a drop go home with you, so nothing is left in the park.

Quiet ads

For towns and libraries

Bring a fairy door trail to your town

Libraries, parks departments and main-street groups already run fairy door trails on printed maps. Hollowfind gives your trail a live map, a stamp passport for every family, and a count of how many people walked it.

Questions

Good questions

Is it free?

Yes. The app shows a small banner ad on the map, and ads are never personalized.

Do I need an account?

Not to look around. Sign in with Google or Apple to claim pieces, log visits or add a fairy house.

Is it for kids?

It's made for families. Accounts belong to grown-ups, and kids explore alongside them.

Can I add my own fairy house?

Yes, if it's yours or you have permission from whoever owns the land. New houses are reviewed before they show up on the map.

I took a piece and didn't scan it. Is that okay?

Completely. Taking a piece is up to you, and so is scanning it. You can scan it later, and it'll still be yours.

Where does it work?

The map works anywhere. Drops start in St. Louis.

Coming soon to iPhone and Android

The first drops are planned for St. Louis parks.
