Tenggarong, up the Mahakam river from Samarinda, is the capital of the Kutai regency, the oldest empire in Indonesia and was once the seat of the Kutai sultanate. The Sultan's palace at the riverside is now a museum where the old royal paraphernalia are kept, as well as an excellent collection of antique Chinese ceramics. Dayak statues can be admired in the yard. A curious thing about the royal paraphernalia is that they display a strong resemblance with Java's court traditions. Every 24th of September, the former palace becomes a stage of dance and music performances given to celebrate the towns anniversary called Erau Festival.
