Al Faihani Palace, Palace in Darin, Tarout Island, Saudi Arabia

Al Faihani Palace stands beside Darin Castle on a rubble hill 3.5 m above sea level in Darin village, Tarout Island. The semi-rectangular castle has two storeys, a southeastern tower and a central water well; its southern half faces the sea, while the abandoned northern half survives only as wall foundations. The complex covers about 8,000 m², with Abbasid-style arches, rooms, warehouses, majlis halls and a rear courtyard.

The building was originally constructed in the 16th century and underwent major renovation between 1884 and 1885 under its notable owner. This restoration period marked a turning point in the structure's condition and its continued use in the region.

Locals know the site by several names, among them Muhammad Pasha Palace, Abdul Wahhab Pasha Palace and Jassim bin Abdul Wahhab Palace. The surrounding quarter, Houta, takes its name from the castle enclosure that housed Ottoman soldiers. The main wooden door bears the date 3 Safar 1303 AH.

The palace and its annexes stand on a 3.5-metre moraine hill in the centre of Darin village, between the Houta and eastern districts, with the sea and Darin port to the south. The castle has two storeys, a southeastern tower and a central water well; its northern half is ruined, so its original outline is visible only in the foundations. The main wooden door bears the date 3 Safar 1303 AH.

In 2014 the Saudi Commission for Tourism and National Heritage excavation recovered a full set of glass, pottery and ceramic vessels, plus potsherds from early Islamic periods. Earlier finds include Umayyad-era coins and coins bearing the two shahadahs, unearthed in the 1970s. A jaw and shoulder fragment were also recovered from the rubble.
