Not only do they date back hundreds of years, they are located all over the planet. First modern planetarium was built in Germany in the early 1920s.

huh? why is that?

i know we here in germany have plenty of them and i would assume that the rest of the world has them too.

Don’t feel TOO bad; it’s not like they’re on every street corner.

Usually you’d go to one on say, a school field trip. But not every school does it. I’ve only been to a planetarium once in my life, and it wasn’t until I was in my 20’s.

Definitely go visit one though; they tend to have really interesting shows about what you can see. And there’s nothing quite like actually looking through a giant telescope with your own eyes. My local planetarium even has special sun-telescopes which allow you to view the sun and solar activity safely during daytime.

Portugal here, yes, we do
