Welcome to Khorramabad, the capital of Lorestan Province in Iran. This beautiful city is situated on the Zagros Mountains and is the largest Luri-speaking city in Iran. With a population of 373,416 persons, Khorramabad is predominantly inhabited by Lur and Kurds. Although not a major tourist destination, it is quite scenic and possesses several attractions, such as five Paleolithic cave-dwelling sites. In the city center, a tall citadel called Falak-ol-Aflak (The Heaven of Heavens), a relic of the Sassanid era, is now a nationally popular museum.
Khorramabad has a rich history dating back to the pre-Islamic era. During the late third millennium B.C. and early second millennium B.C., when Simashki sovereigns were ruling on Elam, for the first time, a fort was built on the peak of a natural cliff to protect the city against its enemies. Six hundred years later, Ellipi kings built a new fort on the ruins of the old one. Simash was the name of the place. It was the capital of the Simashki dynasty. In the texts of historians, Shapurkhast has been considered one of the most important and developed cities of the region during this period. Falak-ol-Aflak castle (Dež-e Shāpūr-Khwāst) was built by Shapur I, the Sassanid king. Probably in the late seventh century AD, Shapurkhast was conquered by the Arabs in 633 AD and destroyed, and the people of Shapurkhast moved to the western part of Falak-ol-Aflak Castle, which offered plenty of water as well as safety. During the reign of the Safavid dynasty, Khorramabad was the administrative center of Luristan Province. In the wake of the demise of the Safavids, after the signing of the Treaty of Constantinople (1724) with Imperial Russia, the Ottomans conquered Khorramabad on the 6th of September 1725. In this period, the city of Khorramabad was limited to environs of Falak-ol-Aflak Castle. This period was the beginning of a migration of people from small villages into Khorramabad. The increase in population led to the expansion of the city and the creation of new districts. Khorramabad Municipality was formed in 1913, and the first city council, consisting of seven members, was formed in 1916.
Khorramabad is located inside a valley and has been surrounded by mountains. The two main mountains around the city are EspiKouh (SefidKouh) and Makhmalkouh. The city is rich in underground resources, and five main springs pass through it. It has one river called Gelal or KhorramRud (new name).

The average annual precipitation is 511.06, and its average annual temperature is 17.21 Celsius.
