Istana Jahar (Museum of Royal Traditions and Customs)

Istana Jahar is a former royal palace in central Kota Bharu, Kelantan, now operating as the Museum of Royal Traditions and Customs. Built in 1855 for Long Kundur, grandson of Sultan Muhammad II, it is noted for its traditional Kelantanese timber architecture, intricate woodcarvings and long central hall. The museum displays Kelantan royal regalia, textiles, weapons and ceremonial objects illustrating the customs and heritage of the Kelantan Sultanate.

Visitors can expect a two-storey timber palace built in traditional Kelantanese style with carved wooden panels, elevated floors and a long central hall. Inside, galleries display royal costumes, textiles including songket, weapons, photographs and ceremonial items explaining Kelantan royal customs and court traditions. The building is located in the Kota Bharu cultural zone within walking distance of other museums and palaces, with indoor exhibition rooms and interpretive panels to explore at a leisurely pace.
