Many buildings in Phuket were built over hundred years since the beginning of the tin boom during the Nineteenth Century. The architectural style, typical of the region, is described as Sino-Portuguese and has a strongly Mediterranean character. Shops present a very narrow face on the street but stretch back a long way. Many, especially on Dibuk Rd (name of Tin)., have old wooden doors with Chinese fretwork carving. Other streets, forming what might be called "Old Phuket", with similar structures are Phang-nga, Yaowarat, Thalang, and Krabi, and a walking tour of the area is easy and delightful. Some other old European-style buildings of note are the Provincial Hall (Sala Klang), the Phuket Courthouse (San Changwat), and Siam City Bank.
