Simone Roux, a historian and specialist in medieval Paris, shows us the capital of France at that time, which was neither a tangle of dirty narrow streets, nor an idyllic city, neat and picturesque, as if straight out of a miniature. The writer tells how residents navigated the city when the streets did not yet have names, and maps and plans did not exist. In this territory, authorities competed with each other - the king, churches, monasteries, feudal lords, and grandiose buildings and majestic structures were not yet architectural monuments, but were visible symbols of their power. Under the pen of Simone Roux, a living picture of a Paris that no longer exists, but which already in those distant times was a harbinger of the modern world, is being revived.
