    Maimun Palace is a royal house for the Sultanate of Deli and becomes one of tourist sites in Medan, North Sumatra. It was built by the Sultanate of Deli in 1888 and the architecture features Malay, Mogul and Italian influences. It has 30 rooms, but only the main room, which features the lavish inauguration throne, is open to public. Here you can check out the modest collection of ceremonial keris and dress up in a traditional Malay costume.

    This palace is one of the most beautiful palaces that still exist in Indonesia. It consists of two floors, each is divided into three parts: the main building, left wing, and right wing. Each floor has 20 rooms. The total of 40 rooms of this palace does not include the prison in the basement, kitchen and bathrooms. On the front, about 100 meters, stands the Mosque of Al-Maksum known as the Great Mosque of Medan. Visitors who come to the palace still have a chance to witness the collection of the kingdom which is displayed in the meeting room, such as the photos of the families, antique furniture gifted by the Dutch, and various types of weapons.

    Maimun Palace is located on Jalan Brig. Jend. Katamso in downtown Medan. This historic building is open to public every day, except when there is a special ceremony or occasion. The back wing of the palace is occupied by members of the sultan's family. The current sultan, Aria Mahmud Lamanjiji, was only eight years old when he was crowned as the 14th Sultan of Deli in 2005, replacing his father, who died in a plane crash. He is the youngest sultan in Deli history. He currently resides in Sulawesi with his mother, and his role is purely ceremonial.
