One is located in the Village of Hanle, on the peak of a western mountain of the Himalayas. It is now the highest obsevatory in the world.
One synonym for astronomical observatories is "space observatories."

The Mayans had, apparently, been expert astronomers, but the first chain of astronomical observatories would be the Muslims in the 9th century. However, Stonehenge is, apparently according to a concept, an observation centre built by the prehistoric people who inhabited Europe.

Astronomy as a natural science was originated in Europe during Renaissance epoch. But its roots go from ancient times from Mesopotamia, China, Egypt, Greece, India, and Central America, where astronomical observatories were assembled.
Astronomical Society of India was created in 1972.
Most large observatories are typically built in remote locations with minimal light pollution and stable atmospheric conditions, such as mountaintops or isolated desert areas. These sites often provide clear skies and reduced humidity, which are essential for astronomical observations. Additionally, high altitudes help to minimize the effects of the Earth's atmosphere on the clarity of astronomical images. Notable examples include the Mauna Kea Observatories in Hawaii and the Atacama Desert observatories in Chile.
Bulletin of the Astronomical Society of India was created in 1973.
It doesn't have to be big telescopes, there does not even have to be a telescope. It is called an observatory because it is a place where astronomical observations are made. Long before the first telescope was made there were observatories.
I do not have access to historical sunset data for a specific location and date. You may be able to find this information by checking historical weather databases, astronomical almanacs, or consulting with local observatories or meteorological organizations.
