During the reign of Reza Shah Pahlavi in the early 20th century, Gholhak Garden underwent further development and modernization, with new buildings constructed and modern amenities added to accommodate the needs of the royal family. The garden became a symbol of wealth and power, reflecting the opulence and grandeur of the monarchy. After the Iranian Revolution in 1979, Gholhak Garden was nationalized and opened to the public as a public park. The garden was renamed Bagh-e Shah, or Royal Garden, in honor of the former royal family. The once-exclusive retreat of the elite was now accessible to all, allowing people from all walks of life to enjoy the beauty and serenity of the garden.
