I had been building dry stone arches for years, before I went to Mallorca in 2005, but I'd always thought you could only build them with flat stones or at least parallel bedded stones - not with roundish irregular stones. When I saw this arch entrance to a well near DeiĆ I realized that arches could be made with almost any kind of stone. And the more difficult the stone looked, the less worked it was, the more genuine it seemed and the more character it had.
