Istana Batu Royal Museum, Royal museum in Kota Bharu, Malaysia.

Istana Batu Royal Museum is a yellow building in Kota Bharu that houses multiple rooms displaying royal artifacts from the Kelantan dynasty. The house is arranged with dining spaces, sitting areas, hallways, and bedrooms that show how the royal household was organized.

The palace was built in 1939 by Sultan Ismail ibni Sultan Muhammad IV as a wedding gift for his nephew Sultan Yahya Petra. The building marks an important moment in the Kelantan royal family's history.

The museum holds belongings of the Sultans of Kelantan: photographs, costumes, artifacts and furniture. The building also served the royal family as a wedding venue and as lodging for royal relatives and guests visiting Kelantan. Sultan Ismail designed the palace himself, and it was opened as a museum on 25 July 1991, the 41st birthday of Sultan Ismail Petra.

The museum opens every day except Friday, from 8:30 a.m. to 4:45 p.m. Plan the visit around that Friday closure, since the building is shut to visitors then. The rooms follow one another through the interior, so allow time to walk the full sequence.

The building was designed by Sultan Ismail himself, who had it built in 1939 as a wedding gift for his nephew Sultan Yahya Petra and his wife Raja Perempuan Zainab II. The palace later hosted royal weddings and housed royal relatives and guests visiting Kelantan.
