Arguably the most famous observatory in the world the Royal Observatory is deserved of its proud heritage. Constructed in 1675 the observatory has been home to some of the very greatest Astronomers in history all of whom made significant contributions to science, plus it’s home to the Meridian allowing you to be in both East and West hemispheres at the same time!
Now a must-see tourist attraction the location has a state of the art planetarium and a gallery of the latest winners of the Astronomy Photograph of the Year competition. However perhaps the most impressive part of this location is the main observatory itself, housing a huge refracting telescope “The Great Equatorial Telescope” which can be observed through during special events organised/assisted by members of the Flamsteed Astronomical Society.
Go visit! And remember to take some monkey nuts with you so you can feed the squirrels in nearby Greenwich Park, just like I used to do with my Grandad many years ago! 😉
