The Frankfurt Green Belt (Frankfurter Grüngürtel) is a circular space that runs around the core city of Frankfurt. It covers approximately 8,000 hectares, which corresponds to about a third of Frankfurt’s city area. The Green Belt of Frankfurt was initiated in 1991 as one of the first green belts in the world with a constitution, at a time when the city did not yet have large growth rates. It is part of the 10,850 hectare green belt landscape protection area.
The green areas encompassed by the Frankfurt Green Belt contain to a large part forest and are excluded from urban development. This results in very strong restrictions for the construction of structures and real estate in all greenish areas of the map shown.
In addition, there are further restrictions due to the nearby Frankfurt Airport: in the areas of landing paths, for example, no apartments may be built for noise protection reasons.
The areas of the green belt also extend into the neighboring areas of the metropolitan area, and create a natural landscape that is interrupted by smaller cities.
