Elche is the City of Palm trees where there are more palm trees that humans! Palm trees are inherent in all of the Elche traditions including a play called Misteri which is performed in the Elche Cathedral; these perfomances are thought to have started in the mid-1500s.
From the Visit Elche website: "With more than 200,000 palm trees, 50,000 of them in the town´s nurseries ready to be transplanted, the Palm Grove of Elche is the largest in Europe. Although, when viewed from a distance, it may appear to be a great forest, it is, in reality, a plantation with an agriculture purpose. Hence the plots of palm trees or their groupings are called "huertos" or orchards. Each of the plots is flanked by rows of palm trees, in such a way that, as seen from the air, they form a grid pattern. The terraces created within the plots have traditionally been dedicated to agricultural production."
