First mentioned in the Liber Census Daniae in 1241, the manor's thick and irregular walls suggest that the building was originally a medieval vassal stronghold. The first known owner of the manor was a vassal of the Danish King Gerhardus de Kouwe who was the mayor of Kau in 1319. Since no one knows what became of this family, historians believe that Gerhardus participated the failed 1343 uprising of St. George’s Night and lost the Manor during the suppression of the Estonians in the aftermath. However, Kau has been a home to warriors, artists, explorers and statesmen ever since. A renowned warlord Heinrich Dücker owned Kau during the Livonian War in the 1560s. The Head of the Estonian Noble Corporation Tonnies Wrangell lived here at the end of 16th century. In the early 19th century Kau was the home to a world-famous explorer, Otto von Kotzebue. In 1906 it became a by-manor of nearby Paunküla, owned by the von Hagemeister family. Triigi manor remained in their possession until its expropriation by the newly independent Republic of Estonia in 1919. In the 1920s and 1930s Kau was owned by a War of Independence hero, the head of Estonian Military Intelligence Colonel Karl Laurits. In 1975, the house was abandoned and left to decay for several decades. In 2007, Mary Jordan and Eerik-Niiles Kross acquired the manor house. Although only a relic of its former self, Mary and Eerik were intrigued by the rich history of the place. Mary—an acclaimed filmmaker and artist—saw the manor's potential and committed herself to breathing new life into the house.
