When the dynasty chose as its capital in 1794, the rulers began to construct a new residence on the site of a 16th century Safavid citadel. The result was Golestan Palace, an opulent complex of 17 grand structures set around a large elegant garden. Within its halls are architectural and artistic marvels, from stunning mirror work to a marble throne and towers that overlook the city. Used by four dynasties, the heritage on the site paints a vivid picture of power and beauty in the heart of Tehran.
