After the mud flood about 300 years ago, people simply built on the new street level. This happened all over the world. - Even though the controllers try to hide the Old World from us, there are still many remnants, even in Germany. Every building that officially dates from the Wilhelminian period (ca. 1850-1900) is in reality a building from the Old World. Our history is fake, there was no Middle Ages, it was invented. In the time of the alleged Middle Ages there was a worldwide civilization with free energy. An advanced civilization that, if we compare our present-day cities with those of the Old World, was far ahead of us!
