Royal Observatory, Greenwich

The Royal Observatory in Greenwich is a place where people can learn about space and time. It's like a big school for grown-ups who want to learn about stars, planets, and clocks.

In the Royal Observatory, there are lots of cool things to see and do. You can go inside a big telescope called a 'Great Equatorial Telescope' and see what the stars look like up close. You can also see lots of old clocks that were very important for telling time a long time ago.

The Royal Observatory is located in a place called Greenwich, which is in London, England. It's a really special place because the prime meridian goes through there - this is like an invisible line that divides the world into two halves, east and west. This is an important line for people who need to know what time it is all around the world.

So, the Royal Observatory in Greenwich is a place where you can learn about space, time, stars, and clocks. It's like a big school for grown-ups who want to learn about these things.
