In the city of Frankfurt am Main, in the state of Hesse, Germany

 Germany’s big financial center is a city of many sides.

========================================================================
(in Frankfurt am Main) The city lies along the Main River about 19 mi. (30 km) upstream from its confluence with the Rhine River at Mainz. Glinting with glass, steel, and concrete skyscrapers, Frankfurt-on-the-Main is unlike any other German city. The focal point of a conurbation of 5.5 million inhabitants, "Manhattan" is a finance and business hub, home to one of the world’s largest stock exchanges and the gleaming headquarters of the European Central Bank; it also famously hosts some of the world's most important trade fairs.

+ Opposite that sci-fi cityscape is the Museumsufer, a neighborhood of museums. Frankfurt am Main (lit. "Frank Ford on the Main") is the 5th-most populous city in Germany. Located in the foreland of the Taunus (a mountain range in Hesse, Germany) the city is the heart of the larger Rhine-Main metropolitan region, which is the 4th biggest metropolitan region by GDP in the EU. Frankfurt is one of the de facto main capitals of the European Union, (alongside Brussels, Luxembourg, and Strasbourg), as it is home to the European Central Bank, one of the institutional seats of the EU, while Frankfurt's central business district lies about 90 km (56 mi.) northwest of the geographic center of the EU at Gadheim in Lower Franconia. Like France and Franconia, the city is named after the Franks.

+ There is evidence of Celtic and Germanic settlements in the city dating from the 1st century BCE, as well as Roman remains from the 1st and 2nd centuries CE. Yet, the first written mention of Franconofurt stems from Charlemagne’s biographer, Einhard. in the late 8th century. The Pfalz (imperial castle) served as a royal residence of the East Frankish Carolingians from the 9th century through later medieval times. In the 12th century, the Hohenstaufen dynasty erected a new castle in Frankfurt and walled the town. The Hohenstaufen ruler Frederick I (Frederick Barbarossa) was elected king there in 1152, and in 1356 the Holy Roman Empire's constitution designated Frankfurt as the site for electing the German kings. Frankfurt am Main was a free imperial city from 1372 until 1806 when Napoleon I made it the seat of government for the prince primate of the Confederation of the Rhine. In 1810 the city became the capital of the Grand Duchy of Frankfurt, created by Napoleon. From 1815, when Napoleon fell, Frankfurt was again a free city, where in 1848–49 the Frankfurt National Assembly met. From 1816 to 1866 the city was the seat of the German Bundestag (Federal Diet) and thus the capital of Germany. After the Seven Weeks’ War in 1866, Frankfurt was annexed by Prussia and lost its free-city status. Only after its integration into a united Germany did Frankfurt become a large industrial city. Until WWII, Frankfurt’s Old Town was the largest medieval city still intact in Germany. The Old Town was mostly destroyed by Allied bombing campaigns in 1944, however, and was later rebuilt.
