Originally built as a 19th-century defensive fort, the Sultan’s Palace was converted into a residential palace by the Sultan Al-Katheri in the 1920s. The sultan wasn’t a subtle man and his house, containing a mere 90 rooms, towers over Sayun like an exaggerated wedding cake. So proud was the sultan of his new home that it’s said he beheaded the main architect in order to prevent him building a copy anywhere else. It now houses one of the best museums in the country.
