Ku Den Museum is situated on Satun Thani Road, opposite the Satun Land Department Office. The two-story building received the influence of western styled architecture; particularly the windows and doors which are of Roman motifs. The roofs were designed in the Thai’s Panya style. The windows were assembled with narrow strips of boards arranged horizontally. The semi – circular clay tiles were used to cover the roofs. The ventilation at the upper-front of the building is decorated with star-shaped designs, imminently influenced by Muslim architecture. Phraya Phuminatphakdi, the former governor of Satun, built it in 1902 as his residence. The building was used as a city hall, though nowadays it serves as a museum housing antiques and artifacts and exhibiting the local art and culture.
