Golestan Palace.

Golestan Palace is located in the old city center of Tehran, the capital of Iran. From the Qajar dynasty to the Pahlavi dynasty, Golestan Palace was always the residence of the Iranian royal family. The palace combines magnificent palaces, tranquil pools, and beautiful gardens, which are the three essential elements of Iranian palaces. Both the exterior and interior of Golestan Palace are extremely luxurious, with the exterior walls decorated with colorful glazed tile mosaics, the interior decorated with sparkling mirror inlays, and exquisite plaster carvings, all of which are impressive.
