Currently, in the urban area of Elche there are a total of 97 different orchards containing about 70,000 date palms, mostly in the east bank of the Vinalopó. This number does not include other large plantations located around the city proper. All together, the number may be close to 200,000 palms. The Palm Grove covers over 3.5 km2 (1.4 sq mi), including 1.5 km2 (0.58 sq mi) within the city of Elche.
The first date palms in Elche could have been originally planted as early as the 5th century BC by Carthaginians who settled in south-east Spain. The Romans introduced the first elaborated forms of agricultural water management. Under the Moors the city of Elche moved from its Roman location 7 km away to its current location. The Moors further developed the irrigation system with the brackish water of the Vinalopó, which is basically the same as the one still in use for the palm orchards. The formal landscape of the palmeral that still exists today was created when the city was under Moorish control between the 7th and 10th century. Following the Reconquista by the Christians (14th century), a local handicraft developed involving desiccated palms and their weaving for processional use in Palm Sunday. Also, improvements were added by the new settlers, such as the construction in the 17th century of Elche's dam in the Vinalopo, some 6 km upstream of Elche, for a better management of the Palm Grove irrigation. Similarly, laws were passed to protect the plantation .
The palm groves form a rather compact group in the eastern part of the town. The boundaries of the plots (horts in Valencian) are rectilinear, so they are mostly square or rectangular (a few triangular) in plan. They were bounded by –nowadays uncommon– cascabots (fences of plaited dried palm leaves), or by plastered walls of undressed stone 1-2 m high, which are still present. The plots contain the houses of the tenants or owners of the land, although these are nowadays mostly in a ruinous condition, since most of them have been purchased by the local council and nobody is living there anymore; for those houses located in plots which have not been bought, they have been mostly deserted by the owners due to the constrained development of such houses originating in the law governing and protecting the Palm Grove.
The trees are planted in single or double rows, following the lines of the ancient –and still functioning– irrigation canals, which are of special interest to the UNESCO as an integral part of the Palm Grove. Seen from the air, the different plots form an irregular grid pattern.
Historically, the orchards were dedicated to the production of dates for human and livestock feeding. The terraces created within the plots have traditionally been dedicated to agricultural production with more valuable species such as pomegranate or vegetables which benefitted from the shade created by the palm trees around. This enhanced agriculture in a region where summer temperatures are consistently above 30 °C and annual rainfall is only about 250 mm (9.8 in).
As the town spread in the 17th century, some of the orchards were cut down. This process was exacerbated with the industrial revolution and the arrival of the railway in the 19th century. The agricultural role was progressively abandoned. By the second half of the 20th century the date harvesting (which takes place by November–December) had become an anecdotal activity mostly for domestic or very local consumption.
However, the orchards had the affection of locals and were kept after their economic function had ended. Progressively, some of them were turned into public gardens while respecting the original lay out. Currently, the Palm Grove´s role is more as a landscape and a cultural asset than as an agricultural site. The latter function focuses on the production of "white palms": desiccated palm leaves for decoration and processional use on Palm Sunday which are sold throughout Spain and even abroad. The palms are a part of the local identity, and so have been historically represented in the town's coat of arms (as white palms).
Individual specimens present in the Palm Grove can grow to a height of more than 30 metres and be up to 300 years old.
A famous palm is the one known as "Imperial Palm" (Palmera Imperial), with 7 stems in the shape of a candelabra. It was named after Elisabeth, known as Sissi, the Empress consort of Franz Joseph, who visited the plantation in 1894 and to whom it was dedicated. By 2014 the Imperial Palm was estimated to be about 170 years old.
Protection and threats
Protection of the Palm Grove remained largely unregulated until 1986, when the Valencian regional government issued the current Law on the Protection of the Elche Palm Grove, regulating the traditional uses and protecting the Palm Grove from any changes potentially affecting its traditional layout and maintenance.
In 2000, the UNESCO designated the Palm Grove as a World Heritage Site citing the transfer of landscape and agricultural practices from one culture and continent to another (Moorish North Africa to Christian Europe).
In 2005, it was discovered that the larvae of the red palm weevil (Rhynchophorus ferrugineus) had infested some trees, laying its eggs inside the stems. Currently the Palm Grove is under management to avoid the spread of the pest using a combination of biological pest control, pheromone traps and approved specific pesticides.
