Originally built during the Ayutthaya Kingdom in the 17th century, Bang Pa-In Palace served as a summer retreat for the Thai monarchs. Over the centuries, successive kings expanded and renovated the palace, incorporating various architectural styles and influences, including Thai, Chinese, European, and even Victorian.
During the reign of King Rama IV (1851-1868), also known as King Mongkut, extensive renovations were undertaken, and the palace was restored to its former glory. Later, King Rama V (1868-1910) further expanded the palace complex, adding new structures and embellishments, turning Bang Pa-In into the magnificent royal residence it is today.
