Grüneburg Park & Palmengarten
This park got its name from a green castle that once stood on the grounds in the 14th century.
Frankfurt is actually a very green city, but most of its parks and woods are relegated to the periphery. An exception is this park in the Westend district of the city. The winding paths of the English-style Grüneburg Park are popular with joggers. Wide lawns invite sunning, picnicking and playing pick-up soccer.
Architecture aficionados should swing by the nearby Poelzig Building (also called the IG Farben Building), designed by Bauhaus practitioner Hans Poelzig in the late 1920s as the headquarters of a giant chemical concern. The U.S. Army moved in after World War II, but since 2001 the giant comb-shaped structure has been part of Frankfurt University.
In the nearby Palmengarten, a beautifully landscaped botanical garden, you can wander among roses and rhododendrons, stick your nose into greenhouses filled with palm trees and orchids or catch a concert, reading or exhibition. There's even a little lake with boat rentals and a tram for tired feet.
