How did they do it? How did they build the great Gothic cathedrals of Europe without the help of modern-day tools and equipment? In Medieval times, it was a complex process involving an assembly line of common laborers, experienced builders and skilled craftsmen; materials such as stone, iron and wood; experimentation and innovation; and time! Lots and lots of time—in some cases, hundreds and hundreds of years!
The Cologne Cathedral in Germany is an impressive architectural masterpiece. As the third tallest church in the world, it is described by the UNESCO organization as an “exceptional work of human creative genius”.
