Golestan Palace, now a museum, was the residence of several shahs of Iran.? It is infact not a single palace but a complex of several building in a large flower garden (golestan) in Tehran. The main building, with it's state rooms and where the last Shah of Iran, Mohammad Pahlavi, was crowned is probably the best known but this smaller building was comfortable living quarters for the royal court. A stream ran beneath it through its vaulted cellar to keep the rooms cool during Tehrans hot summers. Rooms had fireplaces to warm them during winter. As well as the cooling stream was a wind tower to provide cool, fresh air.
