It was not until 1866, under the reign of King Norodom I (1860–1904), the eldest son of King Ang Duong, who ruled on behalf of Siam, that Phnom Penh became the permanent seat of government and capital of Cambodia, and also where the current Royal Palace was built. Beginning in 1870, the French colonial authorities turned a riverside village into a city where they built hotels, schools, prisons, barracks, banks, public works offices, telegraph offices, law courts, and health services buildings. In 1872, the first glimpse of a modern city took shape when the colonial administration employed the services of French contractor Le Faucheur to construct the first 300 concrete houses for sale and rental to Chinese traders.
