The most important architectural complex in Phnom Penh is the Grand Palace, built in the mid-19th century and located on the banks of the Tonle Sap River. The current residence of the Cambodian King Norodom Sihamoni is also situated here, enclosed separately by a wall where visitors can only view from a distance. Along the Tonle Sap River, the grand rooftops and spires of the palace shine brilliantly under the blue sky and white clouds, presenting a majestic sight. At night, the silhouettes of the palaces viewed from the river surface appear quite mysterious.
