The Sa'dabad Complex is a significant cultural and historical site located in Tehran, the capital city of Iran. Nestled at the base of the Alborz Mountains, the complex serves as a testament to the royal history of Iran, especially during the Pahlavi dynasty. Covering an expansive area of about 110 hectares, Sa'dabad features a collection of palaces set within lush gardens. Originally built during the Qajar dynasty in the 19th century, it was later expanded upon by Reza Shah. The complex became a royal residence before the 1979 Iranian Revolution. After the revolution, these palaces were transformed into museums. The complex includes more than 15 museums, the most notable of which are the White Palace (Mellat Museum) and the Green Palace. Exhibits feature royal artifacts, fine arts, and cultural treasures, providing a glimpse into the opulence of the royal era. The surrounding gardens, with their serene streams and pathways, offer a peaceful retreat from the bustling city. Sa'dabad Complex is not only a historical site but also a cultural centre contributing to the preservation of Iranian art and history.
