Many history enthusiasts probably know that the Middle Ages that were sometimes referred to as the ‘Dark Ages’ were not so dark. In fact, these were the times when people started building castles – majestic and complex buildings intended to be a safe retreat in case of attacks. Normans were the leading castle-builders of the period having started their constructions on forts left by the Romans. However, what they probably haven’t taught you at school is that those narrow, spiral staircases were actually built that way for a purpose and for a very practical and thought-out one as well. This interesting fact on the staircases of Medieval castles was posted on a Tumblr account and quickly ignited a fascinating discussion for history lovers.
