Dezful in the context of "Dezful County"

Gundeshapur (Middle Persian: 𐭥𐭧𐭩𐭠𐭭𐭣𐭩𐭥𐭪𐭱𐭧𐭯𐭥𐭧𐭥𐭩, Weh-Andiōk-Ŝābuhr; New Persian: گندی‌شاپور, Gondēshāpūr) was the intellectual centre of the Sasanian Empire founded by the Sasanian emperor Shapur I. Gundeshapur was home to a teaching hospital and had a library and an ancient higher-learning institution, the Academy of Gondishapur. It has been identified with extensive ruins south of Jandi Shapur, a village 14 km southeast of Dezful, along the road to Shushtar in Khuzestan province in southwestern Iran.

The city declined after the Muslim conquest of Persia; the city surrendered in 638. It continued to remain an essential centre in the Islamic period. Ya'qub ibn al-Layth al-Saffar, the founder of the Saffarid dynasty, made Gundeshapur his residence three years before his sudden death in 879. His tomb became one of the most prominent sites in the city.

Chogha Bonut (Persian Choghā bonut) is an archaeological site in south-western Iran, located in the Khuzistan Province. The site is about 20 km southeast of Dezful, and 5 km west of Chogha Mish, another ancient site. It is believed that the site was settled as early as 7200 BCE, making it the oldest lowland village in south-western Iran.

This settlement on the Susiana Plain played a big role in the early Elam civilization. Later, this area became dominated by Susa. The site is important because it preserves a record of preceramic period settlement in Iran.
