Wallanlagen, Public park in Frankfurt, Germany

The Wallanlagen is a ring-shaped park of about five kilometres around Frankfurt's inner city, laid out on the site of the city walls razed between 1806 and 1812. It is divided into seven sections named after former city gates, from the Untermainanlage by the Main to the Obermainanlage. The photograph shows lawns crossed by curved gravel paths, a fan-shaped cobbled area, benches, and two glass-facade towers behind the trees.

The park emerged in the early 19th century after Frankfurt's medieval fortifications were demolished between 1804 and 1812. The former defensive walls were replaced by a public green space that encircles the city.

The seven sections carry names of former city gates and still serve as reference points throughout the city. These names tell the story of Frankfurt's past as a walled town and shape how residents understand their neighborhoods.

The belt is about 100 metres wide and runs five kilometres around the centre; the seven sections are named after former gates, so the Eschenheimer Turm, the only surviving gate tower, marks the Eschenheimer Anlage. The Untermainanlage, the smallest section at roughly 5,000 square metres, links to the Nizza park on the Main. The 1827 Wallservitut keeps the strip free of buildings.

The Wallservitut law of 1827 permanently protects this roughly 100-meter-wide green belt from construction. This makes the park one of Europe's oldest intentionally preserved green belts.
