Constructed simultaneously with the establishment of Rattanakosin in 1782 by King Rama I the Great, the complex covers a total area of 60 acres and comprises 2 major quarters; the Grand Palace and Temple of the Emerald Buddha (Wat Phra Kaeo).

The palace lies to the east of the Royal Grand Palace, it was built during the reign of King Rama IV. In 1868 King Rama V gave Saranrom Palace to his eldest brother, Prince Kroma Phra Chakrabaddibongse. Later this palace has been used as the Ministry of Foreign Affairs where state guests were received. King Rama VI lived here until he ascended the throne when he then returned the palace to the Ministry of Foreign Affairs in 1926.

Saranrom Royal Garden was built in 1868 and the park was later created in 1874. There are many interesting monuments and one of them is the memorial of Queen Sunantha Kumareerat who passed away from a boating accident in 1880 when she was still young.
