Frankfurt is the largest city in the Rhine Franconian dialect region. The city, also officially known as Frankfurt am Main, is an active metropolis and the largest city in Hesse, a federal state in German. It is among the top largest cities in Germany, coming fifth after Berlin, Munich, Cologne, and Hamburg. Frankfurt has a convenient location on the River Main, within the heart of the Rhine-Main metropolitan region, Germany's second-largest metropolitan area. As one of the principal cities during the Holy Roman Empire, Frankfurt has grown to become an active economic, cultural, and financial hub, as well as a diverse city in terms of culture, ethnicity, race, and religion. Frankfurt is famed for being the home of Johann Wolfgang von Goethe, whose house has since been converted into the Goethe Museum. The city is also home to the financial giant, European Central Bank, the reason why it is now a major financial hub in the region. Apart from the financial institutions, Frankfurt also hosts key educational institutions like the Goethe University, the Frankfurt University of Applied Sciences, the iconic Frankfurt University of Music and Performing Arts, as well as the renowned Frankfurt School of Finance and Management. Some of the significant landmark structures in Frankfurt include the medieval-era Römer building near the Saint Nicholas Church, the iconic Hauptwache area that represents the heart of Frankfurt's CBD, the mighty Saalhof, and the beautiful Alte Oper house where operas and other concerts are held. The cityscape of Frankfurt especially looks gorgeous at night, complete with the neon lights and the wondrous skyscrapers.
