The story behind Bosscha Observatory

Why it matters
Why Bosscha Observatory is worth your time
Bosscha is a rare place where colonial-era science is still in use. Wikipedia says it is named after Karel Albert Rudolf Bosscha, a tea plantation owner who gave six hectares of his land for it, and that it was built between 1923 and 1928 with the support of the Dutch-Indies Astronomical Society.
For curious children and older readers alike, the observatory shows how the highlands were more than a tourist resort; they were a base for tea planters, scientists and administrators. Seeing the old domes in a cool hill setting makes a quiet counterpoint to the volcano craters nearby.

How to experience it
The observatory sits at 1,310 metres in Lembang. Wikipedia says its instruments include a Zeiss double refractor with two 60 cm lenses, a Schmidt telescope called Bima Sakti and a Bamberg refractor, which is why the domes are the main sight. Wikimedia Commons photographs show the Koepel Dome and the Zeiss telescope.
Visits are usually arranged through the observatory, and access to telescopes may be limited, so confirm what is open before travelling. Even if you cannot go inside the domes, the surroundings in Lembang are cool and green.
Combine it with Tangkuban Perahu in the same morning, since the road to the volcano passes through Lembang. Carry a layer and an umbrella, because cloud and rain can arrive quickly.
