The palace and its annexes are bordered to the south by a small mosque on a rocky outcrop that gradually slopes downwards until it reaches the sea, where the port of Darin is located.

[12] Darin Castle achieved notoriety following the construction of the palace by Muhammad ibn Abdul Wahhab in its adjacence.

The Houta or Qibla neighborhood is separated from the third district by Al-Hala Island, a small bay no more than 500 meters wide.

In 2014, the research and excavation team of the Saudi Commission for Tourism and National Heritage found a complete set of glass, pottery, and ceramic vessels that likely date back to different eras.

[25] Finally, the castle has a monument on its southern side that chronicles the treaty that King Abdulaziz signed with the British.

As a result, the boundaries of the original castle are only recognizable from the remnants of the thin lines drawn by the foundations of the walls.

Several types of wood were used in the construction of the palace's main support, including Local palm trunks, tree stems imported from India.

[39] Aramco's aerial image shows that the northern half of the castle is divided into three large squares and three smaller ones.

[40] The western strip of the northern half of the castle had a small house and a shop belonging to the Razihan family.

[44][45] The other parts of the building dedicated to military housing and horse stables were gradually demolished with the fall of Ottoman rule in 1331 AH.

[52][53][54] John Gordon Lorimer mentions that it was Rahmah ibn Jabir al-Jalhami who built DarinCastle around 1830 AD, and he also mentions that Rahma bin Jaber al-Jalahmi and the Al-Busmeet[Notes 4] clan could not resist the hostility of the people of Qatif, he was forced to emigrate to Muscat in 1831/1246 AH after the demolition of the Castle.

[58][59] Darin remained abandoned until 1288 AH, when it was visited by the Ottoman governor of Baghdad, Ahmed Medhat Pasha, in his campaign to overthrow the second Saudi state.

[65] The news of Darin Castle being used as a headquarters for Ottoman officers and soldiers is also mentioned in a number of historical documents, including the following text written in 1888 AD.

[68] It is clear from the text that Nafez Pasha transferred half of the soldiers residing in Qatif to Darin, and the number of these soldiers whose stay in Darin Castle was secured was thirty, they take orders directly from the Qatif mayor, this was confirmed by a letter from Sheikh Mubarak Al-Sabah, the ruler of Kuwait, to Colonel Kimball the Acting Political Resident in the Gulf, written on Muharram 10, 1320 AH, contains the following text: In these days, the Turks sent thirty soldiers from Qatif with Ibn Jum'ah to the island of Amayer to stay in it.

The document shows that in that year, the Qatif mayor, Mansur Pasha bin Jumaa, transferred the thirty Turkish soldiers from their permanent headquarters in Darin Castle to Al-Muslimiyah Island, north of Jubail.

Darin Castle contained a private residence for the local administrator, rooms for officers, a number of stores, an artillery shop, a horse stable, and likely a small prison as well.

At the time, it was similar to Ibrahim's Castle in Al-Ahsa, which contained a private residence, the officers' and soldiers' room, warehouses, an artillery shop, a prison, a hospital, and a small religious school.

[73] It was gifted by the first Saudi state to Muhammad ibn Abdul Wahhab al-Faihani to live with his family after he emigrated from Qatar following the Ghariyah War.

[78] When the tribes of Qatar, led by Nasser bin Jabr and the Abu Kawara family, led by Muhammad bin Abdul Wahab al-Faihani, who was no less wealthy and inclined to rule and preside than Sheikh Qassim bin Thani, came to Qatar, he caught them in Qasr Rabia in the town of Gharbia in Qatar, the hometown of Sheikh Muhammad al-Faihani [Notes 11][79] From there, Al Faihani moved to Tarout Island and was gifted the palace by the first Saudi state after being built on old foundations.

His son Jassim continued to live in the Castle and after his death it gradually became the property of members of the Al Faihani family.

[87] Due to the richness of the crescent-shaped ribbon in the center of the castle in terms of relics and skeletons, a fairy tale has been circulating among the people of Darin that explains why they found so many pottery vessels, and skeletons that they are not used to the non-Islamic burial method, according to this myth, the inhabitants of the island of Darin were once infidels who were ravaged by God three times, with each ravage forming a layer or a destroyed city according to their beliefs.

[89] After the palace collapsed, the Tourism and Antiquities Authority in the Eastern Province began cleaning and removing rubble and debris.

Most of its walls were collapsed, as well as the decorative carvings that the palace used to contain, all that remains of the castle is the tower, which has also gradually fallen into decay due to erosion and neglection.
