South African Astronomical Observatory
The South African Astronomical Observatory was founded in 1820. It is the national centre for optical and infrared astronomy in South Africa. Its primary role is to conduct fundamental research in astronomy and astrophysics by providing a world-class facility to scientists. The SAAO also promotes astronomy and astrophysics in Southern Africa by sharing research findings and discoveries and participating in outreach activities to enthuse citizens about physics and astronomy. Â The main building, built 1825-8, is in the Greek Revival style and dominates the property and facing a lawn to the South which forms an axis along which are smaller buildings, most dating from the Victorian period.
In the early 1800s, accurate navigation was vital for ships sailing between Europe, Asia, and the Cape Colony. Determining longitude at sea required precise star charts and reliable timekeeping. To enhance global navigation, the British sought a southern hemisphere equivalent of the Greenwich Observatory in England.
A site just outside Cape Town was selected for several reasons:
- It had mostly clear skies throughout the year.
- It was remote enough at the time to avoid light pollution from the city.
- Its proximity to the sea made it ideal for maritime navigation research and ship communication.
