From Regout to Céramique
A route of its own past what is left of the pottery: the factory gate of De Sphinx, a passage with thirty thousand tiles, tile panels on a facade and in the station hall, and the two halls of the Société Céramique.

Forty-five pearls between the Vrijthof and Wyck: a cannonball in a facade with a date that can't be right, the oldest city gate in the Netherlands, a Roman bathhouse in the paving, and seven places where you lay an old print or photo over today's city.

All pearls
Tap a pearl for its riddle. You only get the story and the spotting question once you're standing there.
Your plate wall
For more than a century, Petrus Regout's De Sphinx and the Société Céramique made plates here for half the world. That's why in Maastricht a right answer earns you a plate in their style: a red rim full of flowers and tendrils, and in the centre the pearl's motif.
A route of its own past what is left of the pottery: the factory gate of De Sphinx, a passage with thirty thousand tiles, tile panels on a facade and in the station hall, and the two halls of the Société Céramique.

From the Hoofdwacht past the spot where d'Artagnan fell to the rondels of the Jekerkwartier and the Helpoort, almost eight hundred years old.
Just off the train? Say where you need to go, and from Maastricht station the app plans a walk with a ten, twenty or forty-minute detour past pearls.
One tap and the app walks with you: the map turns with the way you're facing and a voice calls out the turns, so your phone can stay in your pocket.
Maastricht in 1649
Joan Blaeu drew Maastricht in 1649, between two sieges: that of Frederick Henry in 1632 and that of 1673, in which d'Artagnan fell. In the app his map lies over today's city, bent into place at fifty points, so that his streets fall on yours to within about five metres. Go on, move the glass over the city.
