In the right front corner room of the palace, which opens to the outside, is a collection of the palace's most prized art, including the Phra Bang, cast of a gold, silver and bronze alloy. This Buddha stands 83 cm tall and weighs around 50 kg. Legend has it that the statue was made around the 1st century in Sri Lanka and was later gifted by the Khmer king to his son-in-law : King Fa Ngum in 1359.

The Siamese twice took the image to Thailand in 1779 and 1827, but it was returned to Laos by King Mongkut in 1867. There are rumours that the one on display is a copy and the original is stored in Vientiane or Moscow. It is said the real one had gold leaf over the eyes and a hole drilled through one of its ankle. Also in the room are another Buddha, engraved with large elephant tusks, and three beautiful saew mâi khán (embroidered silk screens with religious imagery) that were crafted by the Queen.

On the left of the Entrance Hall, the secretary's reception room is filled with paintings, silver and china that have been presented to Laos as diplomatic gifts from Myanmar, Cambodia, Thailand, Poland, Hungary, Russia, Japan, Vietnam, China, Nepal, United States, Canada and Australia. These objects are grouped by "socialist" and "capitalist" countries. One exhibit donated by the USA is a piece of Moon rock obtained by an Apollo mission.

The next room to the left was once the Queen's reception room. Large royal portraits of King Savang Vatthana, Queen Khamphoui and Crown Prince Vong Savang, painted by Russian artist Ilya Glazunov in 1967, are hung on the walls. There are friendship flags from China and Vietnam and replicas of sculpture from the National Museum, New Delhi.

In the far rooms are the royal family's bedrooms and living quarters. The bedrooms have been preserved as they were in 1975 when the King was forced from the palace. There is a dining hall and a room that contains royal seals and medals.

The Throne Room contains the Crown Jewels of Laos.
