This school is built on a floating platform and bobs about gently off the coast of Lagos in Nigeria. It has 2 big classrooms on the top floor and space for an assembly at the bottom! Best hope none of the students get seasick!
This school (and the village it's part of) is hidden away inside a gigantic cave in China. It's a bit gloomy looking - but the echoing is great for choir practice, and the bats and lizards are perfect to study in biology class.
The Green School is made completely out of bamboo and built into a jungle in Indonesia. It's completely powered by solar panels and has no walls! Yep...no walls!
This school is in the desert in New Mexico, USA. It's not much to look at from the outside, but it doubles up as a fully functioning nuclear bomb shelter. In the event of nuclear war it could shelter up to 2,160 people!
It's almost all underground, in fact the entrance in this photo is the only part you can see from the surface!
This is a real life school to study Witchcraft, based in Salem in the USA. You can learn about pagan history, religion and other witchy things.
It's not as cool as Hogwarts, but you can take courses online - so a bit more convenient than catching a train from Platform 9 and 3/4.
