First built in the 1860s and modified over the decades, the Royal Palace has served as the official residence of Cambodia's kings for over 160 years. While the palace is open to visitors, it still functions as the residence of King Sihamoni, and parts of the massive compound are closed to the public.

The top draw is the Silver Pagoda, a beautifully crafted structure built of wood in 1892, and rebuilt in 1962, that takes its name from the 5,000 gleaming silver tiles that cover its floor. It also houses many national treasures, including the Emerald Buddha.

The walls of the gallery enclosing the pagoda are adorned with colorful frescoes depicting scenes from the Reamker. Nearby is a library building, a bell tower, several stupas, and a scale model of Angkor Wat.

The most striking building in the palace complex is the Throne Hall, an ornate colonnaded Khmer building topped by gilded spires. The public is not permitted to enter the building, which is still used for religious and royal ceremonies, but you can glimpse the three thrones and colorful ceiling frescoes inside by peering through the open doors and windows.

Other buildings of interest include the Bronze House, the Moonlight Pavilion, and an incongruous iron pavilion gifted by Napoleon III.

Tour guides wait by the entrance and can be helpful as the buildings in the palace complex are poorly labeled and without descriptions.

A dress code - shoulders and knees covered - is strictly enforced. Shoes and hats must be removed before entering some buildings.
