For centuries, the legendary Plan of Saint Gall has inspired and inspired architects, historians and archaeologists all over the world, as it is considered the oldest architectural drawing in the Occident. However, this significant plan was never realized – at least until June 2013, when some 40 craftsmen, archaeologists and historians in Meßkirch on Lake Constance began working on the plan, using only the means and methods of the early Middle Ages. In addition to dwellings and craftsmen's huts, a hospital and three(!) breweries, the plan also includes a huge abbey church measuring around 70 metres in height. The construction time will be more than 50 years. Besides the first documentary about the beginnings, this is the second (cinema) film about the years 2016-2018, produced in high quality 4K/50p.
