Fort Provintia or Providentia, also known as Chihkan Tower (Chinese: 赤嵌樓; pinyin: Chìkǎnlóu; Pe̍h-ōe-jī: Chhiah-khám-lâu), was a Dutch outpost on Formosa at a site now located in West Central District, Tainan, 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.

[3][4] The fort's name derives from the Taiwanese aboriginal village recorded by the Dutch as Sakam,[a] which has developed into the modern-day Tainan.

[1] In addition to the site's architectural and artistic significance, its library of dictionaries and business transactions documents the Siraya language spoken by the native inhabitants of the region during Dutch rule.
