The mostly empty hilltop palace overlooking Pangkalan Bun Park celebrates three architectural traditions of the sultans' assorted wives: Chinese, Dayak and Malay. Built in 1806 (and rebuilt in 1990 after a deranged woman burned it to the ground) it is not yellow, but was traditionally draped in yellow fabric.
Nearby, rambling Istana Pangeran Mangkubumi , built to house the sultan's seven daughters, fights against gravity among well-kept gardens.
