The palace stores a collection of properties of the last sultans. In the reception area, life size figures of the sultan and his courtiers welcome the visitor. Inside the palace, one can admire the gold plated royal throne and a duplicate of the royal crown. The original gold crown has been brought to the National Museum in Jakarta. Large photographs of the last sultans decorate the walls of the palace.
The last sultans formed a part of the Dutch establishment. Much of the decor in the palace is European. A big attraction is Komet, a large German music player, whose perforated metal disks tinkle tunes of Mozart, Beethoven and Strauss, brought by the sultan from a visit to Europe in 1896. People say that there are only two left in the world.
Close to the palace, at the banks of Siak river is the Royal Mosque.
