Cathidrals

Cathidrals were places of learning from the bible. It was kind of weird they would build weird shapes to make all the weight to go down. the shapes would be be like an oval with a horizontal line at the bottom but with a point at the top. and to keep the roof up they would build something called a vault witch is som half ovals overlapping to make a strong foundation. After that they would something like concrete on top and then after that dries they make them in lines to hold up the whole roof.
