Pearl Palace (Persian: کاخ مروارید; Romanized: kakh-e Morvarid / Kāx-e Morvārid), also known as Shams Palace[4] (Persian: کاخ شمس; Romanized: kakh-e Shams / Kāx-e Šams) is an estate in Iran, designed by Taliesin Associated Architects (Frank Lloyd Wright Foundation)[3] on instructions from princess Shams Pahlavi, elder sister of Mohammad Reza Pahlavi, the last Shah of Iran.

][5] The Taliesin Associated Architects (Frank Lloyd Wright Foundation) had three buildings built in Iran which include the Damavand Higher Educational Institute (presently known as Payam-e Nour University's Tehran campus), the summer residence of Shams known as Mehrafarin Palace in Chalus (presently occupied by the local police), and the most prestigious, the Pearl Palace.

[3][7] The building is around 1,499.9 square metres (16,145 sq ft) and made of concrete, with two main domes and a "ziggurat" style structure, all connected by stairs and a large ramp.

[3][7][8] After the Iranian Revolution, the Mostazafan Foundation seized all assets owned by the royal family, including Shams Palace.

[9] Small parts were opened to the public (in 2015) as a result of pressure from the Ministry of Cultural Heritage, Handicrafts and Tourism.
