The Madras Observatory was an important place for studying the stars and the Earth. It began as a private observatory set up by William Petrie in 1786. Later, it was moved and managed by the British East India Company in Madras, which is now called Chennai, starting in 1792.

The main job of the Madras Observatory was to help with navigation and mapping. It did this by recording the position of places and keeping accurate time. Over time, the observatory also watched the stars and studied changes in Earth’s magnetic field.

The observatory worked for many years, from about 1792 until 1931. One of its biggest achievements was making a detailed list of many stars, which helped scientists understand the night sky better.

History

The observatory c. 1838

The Madras Observatory began as a small private observatory set up by William Petrie in 1786 in Madras, now called Chennai. After Petrie gave his instruments to the government, an official observatory was built in 1792 to help with navigation and mapping.

The observatory made important discoveries over the years, such as measuring the positions of many stars and studying Earth’s magnetic field. It also helped keep accurate time for the city. The observatory closed in 1931, but the special granite pillar still stands today.
