Ilam Province is one of the 31 provinces of Iran.Covering an area of 19,086 square kilometers include Ilam, Mehran, Dehloran, Darreh Shahr, Sarable, Eyvan, Abdanan and Arkwaz cities.
The province of Ilam is one of the 30 provinces of Iran. Located in the extreme west of the country with its 19 086 km² area, it is located in an elevated and mountainous area. The capital of this province is the city of Ilam and is bordered by Iraq to the west, to the south by the province of Khuzestan, to the east by the province of Lorestan and to the north by the province of Kermanshah.
In terms of climate, Ilam has unique climatic conditions, that is, the seasons at Ilam become entangled as long as the peaks of high, low, or temperate temperatures are consistently high. While in the north of the province, the mountain's cold, snowy air dominates, temperatures are becoming milder towards the south and the mountain scenery becomes green plains with a pleasant and fresh nature. Despite the recession of the nomadic life in Iran, half of the inhabitants of this province still lead a nomadic life and this could allow the development of nomadic rural tourism.
The Majareh cave, the bat cave, the thermal springs of Dehloran, the wild landscapes of the natural parks of Abdanan, the waterfalls of Marbareh, the forests and hunting areas of the Mehran region are among the natural attractions of this region. To this list can be added the forests of Chaghasabz, Khouran, Kabir-kouh and Tarijanau, which form unique, superb biosystems, notably because of the endemic plant species of the region.
The province of Ilam, a region inhabited for millennia, now has five major cities, renowned for their very ancient history, and ecotourism, the main source of tourism revenue for the province, mainly because of the region's forests.
The chief town of the province of Ilam is the city of Ilam, a valley town surrounded by mountains covered with forests. The climate is cool and dry in summer and cold in winter. This city is also famous for its beauty, marked on one side by its geography propitious to ecotourism and on the other, by its history thousand years old. Ilam is surrounded by archaeological sites but also places of pleasure and excursions, such as Tangeh Arghavan, skirted by a river of mountain and located 3 km in the north-east of the city on the way of the gorge "Ghouchali" , whose floral and lush variety, including its famous purple flowers make it a magical landscape. This magnificent gorge is the main hiking area for locals. As for the more recent historical sites, one can mention the citadel of Vali or Ghal-e Vali. This citadel, whose origins remain unknown, was renovated in 1907 by the architect Hadj Darvish, on behalf of Gholamreza Khan, influential politician of the time, to become a small castle, which, first built in a open space, was then surrounded by many buildings.
The city of Eyvan is the second largest city in this province. Located in the north-west of the province, at an altitude of 1170 meters, it is best known for the richness of its protohistoric and archaeological heritage, including dating from the iron and bronze ages. The archaeological sites concerning these times are mostly tombs. Important monuments of this city, such as the Fire Altar of Siaggol, the site of the Reno Gorge and Kushk or the Shirin Arch and Farhad, monument symbolizing love and nostalgia and dating from the Sassanid period, tell the story of the culture and civilization of this town and region inhabited since the Iron Age.
Dehloran is the third largest city in this province. Since always known under the same name, this city is located at the foot of Dinarkouh mountain. The archaeological remains found in this city and its surroundings show that it was inhabited since the Iron Age and that it was a very important city during the Sassanid period. The presence of dozens of ancient archaeological hills also proves this antiquity. Geographically, Dehloran is one of the strategic areas of the province of Ilam and this particular location has always been a factor of destruction in its history. The latest illustration of this situation was the Iran-Iraq war where this city was the most affected in the whole region. After the end of the war, this city was rebuilt and became a tourist center. Economically, Dehloran is also rich in oil and gas wells, although most of its inhabitants are devoted to agriculture.
The fourth largest city of this province is the city of Darreh-Shahr, also a historic city, which has been destroyed several times during history. Among these attacks, we can cite those successive Assyrians during Antiquity and that of the Arabs in the seventh century. According to some archaeologists, the current Darreh-Shahr is the ancient city of "Madaktv", one of the capitals of the Elamites. Darreh-Shahr was thus the first Elamite city razed during the invasion of Assurbanipal, the last Assyrian king. This city was rebuilt during the Parthian period and flourished under the Sassanid reign. Archaeologists have thus been able to bring to light the remains of a Sassanid city, not far from the present city, whose intersections, streets and pedestrian crossings, drawn with remarkable precision, show the importance. The city of Darreh-Shahr is located at the foot of Kabirkouh mountain, alongside the beautiful Sassanid city, the beautiful river Seymareh. The region is rich in water, agriculture and livestock are well developed.
The last major city in the province of Ilam, Shirvan Tchardaval, is also an ancient historic city, whose past dates back to the protohistoric period. This city was also important during the Sassanid era and many remains of what was the ancient city of Shirvan in the Sassanid era are still to be seen north of the Seymareh River.
