Since 90: A settlement was established by Roman citizens at the Enz river near the modern Altst�dter Br�cke (old town bridge). Archeological surveys have unearthed several items from that period which are kept and displayed in the Kappelhof Museum. The settlement was located where the Roman military road connecting the military camp Argentoratum (nowadays Strasbourg in France) and the military camp at Cannstatt (now a suburb of Stuttgart) at the Upper Germanic Limes border line of the Roman Empire crossed the Enz river. This place was known as Portus (river crossing, harbor), which is believed to be the origin of the first part of the city's name "Pforzheim". A Roman milestone (the so-called 'Leugenstein') from the year 245 and later excavated at nowadays Friolzheim shows the exact distance to 'Portus'; it is the first document about the settlement.
259/260: The Roman settlement 'Portus' was destroyed completely, as the Frank and Alemanni tribes overrun the Upper Germanic Limes border line of the Roman Empire and conquered the Roman administrated area west of the Rhine river. From then on, over an extended period of time historical records about the settlement are not available.
6th/7th century: Graves from this period indicate that the settlement had been continued.
1067: The settlement of Pforzheim was mentioned for the first time in a document by Henry IV, Holy Roman Emperor as "Phorzheim". Visits to Pforzheim by Heinrich IV in 1067 and 1074 are documented.
Before 1080: The "old town" of Pforzheim was awarded market rights (Marktrecht). At that time Pforzheim belonged to the estate of Hirsau Monastery, according to monastery documents.
From 1150: Establishment of the "new town" west of the "old town" at the foot of the Schlossberg (palais hill) under Margrave Hermann V.
1200: The town charter of the "new town" was mentioned for the first time in a document. The "old town" continued to exist as a legally independent
