Golestan Palace is the finest historic building in Tehran and the finest example of Qajar-era Persian architecture in the country. The complex — a UNESCO World Heritage Site since 2013 — consists of a walled garden and 17 structures built over 131 years of Qajar rule (1794–1925), ranging from the intimate mirrored halls of the inner palace to the ornate tiled exterior of the Marble Throne.
The tiled outer walls and gatehouses are extraordinary — covered in the geometric floral tile work that characterised Qajar aesthetics, in blues, greens, and yellows that have barely faded in two centuries. Inside, the rooms progress from Persian to European to a hybrid that is entirely its own: Venetian chandeliers, Belgian mirrors, and French clocks coexisting with Persian carpet, tile, and craftsmanship. The Chehel Sotoun (Hall of 40 Pillars) and the Salam Hall are the grandest spaces. The museum sections include royal portraits, Qajar lacquerwork, and the ivory throne used for court audiences.
Allow two to three hours. The palace is crowded on Friday afternoons and public holidays; visit on a weekday morning for the best experience.
