A landhuis (Dutch for "mansion, manor", plural landhuizen; Indonesian: rumah kongsi) is a Dutch colonial country house, often the administrative heart of a particuliere land or private domain in the Dutch East Indies, now Indonesia. Many country houses were built by the Dutch in other colonial settlements, such as Galle, Cape Town and Curaçao, but none as extensively or elaborately as in the Residency of Batavia (an area that includes parts of modern-day Jakarta, West Java and Banten provinces). Much of Batavia's reputation as "Queen of the East" rested on the grandeur of these 18th-century mansions.
