Bosscha Observatory is the oldest observatory in Indonesia. The observatory is located in Lembang, West Java, approximately 15 kilometers (9.3 mi) north of Bandung. The observatory is named after the tea plantation owner Karel Albert Rudolf Bosscha, son of the physicist Johannes Bosscha and a major force in the development of science and technology in the Dutch East Indies, who granted six hectares of his property for the new observatory. Construction of the observatory began in 1923 and was completed in 1928. Since then a continuous observation of the sky was made. In 1959 the observatory’s operation was given to the Institut Teknologi Bandung and has been an integral part of the research and formal education of astronomy in Indonesia.
