With its unique Islamic pattern and engineering designs that embodied the era of its construction in around the mid fourteenth Hijri century, the King Abdulaziz Palace in Al-Muwayh Governorate in Al-Taif can be seen as an architectural masterpiece that became one of the historical monuments in the Kingdom of Saudi Arabia. The King Abdulaziz Palace is characterized by its central location among adjacent villages and its proximity to the Hajj road at that time between old Al-Muwayh (Al-Muwayh Al-Qadim) and the new Al-Muwayh, where its area is estimated at 14,900 square meters and it is almost 185 kilometers away from Taif to the east and is surrounded by a wall of solid black rocks with a height of 4.5 meters and a thickness of 100 centimeters, as its construction followed the identity of the area with the pattern of old Saudi palaces. The palace is secured with two watchtowers and two castles from the eastern and northern sides, and is composed of a wall with a yard for the Royal compartment that is built with rock and gypsum, in addition to having protocol halls for receiving guests and visitors,and headquarters for prominent figures and accompanying government institutions. Visitor of the palace can notice its rectangular shape that is to the west of the castle and has two entrances: the main entrance that includes housing and service units, dining room, bedrooms, bathrooms, and a palace for guests, in addition to containing several rooms overlooking an uncovered yard with a main entrance from the northern side and two wells that secured water for its residents, a mosque, several towers, room for preparing coffee, bedroom and a gas station to fill up cars, and another residential palace in the middle of the castle with six rooms. Al-Muwayh, more than 85 years ago, had the honor to receive the late King Abdulaziz in its first visits in 1360 Hijri to the palace that was established in 1357 Hijri, where the palace was known as the top main stations of the late king upon his arrival for Hajj, Umrah, spending the summer or hunting, where he also used to meet with the citizens at the palace during his annual visit to the area.
