fortified field posts at places like Antjol, Jacatra, Noordwijk, Rijswijk, Angke, and Vijfhoek; most of which were established in the middle 17th century. The first houses were simple structures, but as time went by, these became opulent country houses in luxurious pleasure gardens, often with their own music pavilion and belfry. Indies Style The Indies Style appeared very pronounced in the country houses of the Dutch Indies. This style appeared in late 18th-century and gradually adapted to the tropical climate. The style can be divided into three major archetypes: Dutch Style country houses, Transitional Dutch Indies country houses, and Indies style country houses. At least one of each of the styles survived as of 2015. Dutch Style country houses Country houses in the Dutch Style (Nederlandse stijl) were popular between 1730 and 1770. They are typically a two-story structure of near replicas of their Dutch counterparts. The Dutch influences are evident in the hipped roof, closed and solid facade and high windows. They often came with belfries, a musical pavilion and a European pleasure garden. The only concession to the tropical climate is the relatively large roof overhang compared with the originals. Unlike their Dutch counterparts, Batavian estates included extensive ancillary quarters to accommodate servants, often in the rear of the house. The interior was usually larger than its Dutch counterpart, with a much taller ceiling. Samples are Weltevreden country house, Groeneveld House in Condet, Reynier de Klerck country house (now the building of the National Archives of Indonesia), and Jan Schreuder country house. Transitional Dutch Indies country houses These Nederlands-Indische stijl, appeared between 1750 and 1800. Their structure and form show acculturation to the tropical climate. Still a two-story structure, the facades are protected from the sun and heavy rain by a larger overhanging roof on all sides. The roof profile resembles the local joglo-style roof traditionally reserved for Javanese noblemen. The upper floor is usually reached by an external staircase and often the central portion was left open for maximum ventilation; as well as tall windows with louvered shutters. The style was also popular in Sumatra. Samples include Rumah Cililitan Besar (1775), which is still in existence, although deteriorating. Other examples are Pondok Gedeh country house and Cengkareng country house. Indies-style country houses Also known as Indo-European house (Indo Europeesche Stijl) or Indische stijl, this type appeared between 1790 and 1820. The form represents the fusion of Dutch
