Since 1962, the five-star Parsian Esteghlal International Hotel which was first named as the Tehran Royal Hilton Hotel has been hosting countless guests, events, and seminars. Situated in the vicinity of Alborz Mountain Ranges, the twin West & East Towers guests have access to some of Tehran frequently-visited spots as well as an unobstructed perspective of the whole city.

Designed by Heydar Ghiai who was known as a pioneer of modern architecture in Iran and noted British architect Raglan Squire who designed Hilton hotels, the 70,000 square-meter property used to be a first-of-its-kind hotel in the Middle East, both in scale and magnitude. Fascinating with the early sunrise accompanied by the cool gentle breeze, the complex features two buildings with 504 mountain and city-facing rooms, 48 junior and royal suites, and the pillar-free Darya-i-Noor Hall with the capacity of 850 guests.
