Mainhattan, Financial district in Frankfurt, Germany

Mainhattan is the nickname for Frankfurt's skyline, above all the high-rises of the Bankenviertel, the central business district on the north bank of the Main. The name joins the river Main with Manhattan. Alongside the towers, the skyline takes in the Imperial Cathedral of Saint Bartholomew and St. Paul's Church. The first tall buildings went up in the 1960s.

Growth began in the 1960s when banks and financial companies chose to establish offices in the area. This concentration of institutions gradually transformed the district into a major European financial hub.

The name is a portmanteau of Main and Manhattan, coined in the 1960s alongside "Bankfurt" and "Krankfurt" as a derisive label during the Frankfurt housing struggles. Since the 1980s it has turned into a friendly nickname used by locals and visitors alike, and it now appears in tourism advertising and in club names such as the Mainhatten Skywheelers. Since 1996 the Wolkenkratzer-Festival has been held at irregular intervals.

The skyline is best viewed from the opposite bank of the Main, from the Sachsenhausen side, where the towers rise behind the river. The Mainufer promenades on both banks connect the district with the city centre on foot. The riverside paths are largely level and open to pedestrians and cyclists.

The headquarters of the European Central Bank sits in this district and influences monetary decisions across the Eurozone. This presence gives the neighborhood economic importance that extends well beyond the city itself.
