Fort Provintia or Providentia was a Dutch outpost on Formosa at a site now located in the West Central District of Tainan in Taiwan. It was built in 1653 during the Dutch colonization of Taiwan. The Dutch, intending to strengthen their standing, sited the fort at Sakam, about 2 miles (3.2 km) due east from modern-day Anping. The fort was surrendered to Koxinga and later destroyed by an earthquake in the 19th century. It was rebuilt as Chihkan Tower (Chinese: 赤崁樓, p Chìkǎnlóu, w Ch'ih4-k'an3 Lou2; Hokkien: poj Chhiah-khám-lâu) afterwards.[when?]
