There are stone spirals, if those count. One on the big table-land between San Juan de Ortega and Burgos, looking out over the city. A beautiful and remote one way up above the treeline on the camino from Santiago de Peñalba, above Ponferrada. there are at least two more I know of, but it would spoil a lovely surprise if I told where they all were, no?
The one between Terradillos de Templarios and Moratinos is a small Cretan-style labyrinth that´s not always well-maintained. Lots of people stop to rest at the little wayside well (there are benches to sit on, but the water isn´t potable), many don´t even realize the stones form a design.
But others evidently know very well what a labyrinth is. They leave little offerings behind, in the center. Small rites go on there every equinox and solstice, just to keep the Vibe going. It´s nice having a labyrinth nearby (I really like the German word for labyrinth: Obulus.)
