Bosscha Observatory is the oldest observatory in Indonesia. Located at the northern hilly side of Bandung, the 1928-made observatory has served the astronomical research since the Dutch East Indies period. Bosscha is named after Karel Albert Rudolf Bosscha, the tea plantation owner in Malabar, who granted six hectares of his plantation to the Dutch-Indies Dutch-Indies Astronomy Association to build the observatory. Since 1959, Bosscha has been an integral part of the Department of Astronomy, Institut Teknologi Bandung.
