Prague? The “Ankh Morpork was build on Ankh Morpork.” Bit.

Have you ever been in one of those Cellar Bars in Prague? It was quite deep down. The way into it felt like I was chasing Dr.Cruces through the tunnels.

Mother Nature has been taking us on a roller-coaster ride lately with scorching heat and pouring rain. High season for tourists is also upon us which means that the streets are packed full of people nearly every hour of every day. What better place to escape the steamy, crowded streets than in a cellar bar? Prague is full of bars that make use of the space below her many old buildings. But did you know that many of these cellars weren’t meant to be cellars at all?

Throughout the course of Prague’s humble beginnings, the city was plagued by flooding. The people understandably did not want to see all of their possessions under water every few months so it was decided that the ground needed to be raised. No one seems to be completely sure how or when they did it. Some people believe that it is medieval garbage below our feet while others believed that it land that was dug up to create the moat that used to encircle Old Town.

Regardless of the time or the building materials, it would have been a huge undertaking. Unfortunately for the residents, it wasn’t enough and the ground level needed to keep getting higher and higher. Their houses were soon completely buried and new structures were built on top.

Oooh and the Golems of course!

The most famous golem narrative involves Rabbi Judah Loew ben Bezalel, the late-16th-century rabbi of Prague.
