The Sa'dabad Palace Complex, a grand estate in Tehran, was originally built by the Qajar monarchs in the 19th century as a summer residence. It was later expanded and became the residential complex of the Pahlavi family in the 20th century. After the Islamic Revolution, this historical complex was transformed into a museum, allowing the public to explore its rich history and architecture. Today, it stands not only as a testament to Iran's royal past but also as a cultural hub that showcases the nation's art, history, and evolution.
