Most famous medieval cathedrals are in Europe (where the Christians were), and they were built between about 1000 and 1600 AD, during the Middle Ages. There are cathedrals all over Europe, in Spain, in England, in France, in Germany, and in Italy. The architecture of cathedrals is based on the old Roman basilica.

According to the Pythagorean Theorem, the sum of the areas of the two red squares, squares A and B, is equal to the area of the blue square, square C. for a right triangle with sides of lengths a, b, and c, where c is the length of the hypotenuse. Although Pythagoras is credited with the famous theorem, it is likely that the Babylonians knew the result for certain specific triangles at least a millennium earlier than Pythagoras.
