Wiesbaden's walkable green oasis in the middle of the city

"Climate box" on the Kochbrunnenplatz

The city of Wiesbaden has opened the so-called "Climate Box" on Kochbrunnenplatz in the city center. The walk-in experience space raises awareness of climate issues in a vivid way and makes heat resilience tangible. At the same time, it enhances the quality of life in the city center.

Heat stress in cities is increasing significantly due to climate change. The "climate box" makes it possible to experience how climate adaptation can succeed in urban areas - vividly and in the middle of the city. It shows how greening can improve the health, well-being and quality of life of residents, even in hot weather.

The temporary installation provides a green oasis of around 35 square meters for pleasant cooling in the hot summer months. A variety of climate-friendly plants, a shady awning, seating and a spray mist system create a place to relax in the middle of the urban space.

The "climate box" is open daily from 9 a.m. to 7 p.m. on Kochbrunnenplatz and will remain there until the end of September. In summer 2026, it will be used again at a new location in Wiesbaden.

Come in, take a deep breath and cool down

Why do cities heat up so much in summer - and how can plants, shade and water improve our urban climate? A visit to the climate box is all it takes to experience the difference:

pleasant air through misting
Shade through greenery
Seating to take a break

The installation is complemented by four information boards that convey key aspects of climate adaptation.

Survey on cooling in the city

An accompanying survey on the topic of "Cooling and climate adaptation in the city" invites visitors to the Climate Box to contribute their opinions.

The concept is ecologically well thought out. Native perennials, shrubs, flowers and trees were selected, taking into account heat tolerance and different water requirements. This ensures a pleasant microclimate, adds colorful accents and provides food for insects. Peat-free soil was used to help protect the moors.

A joint project

The "Climate Box" was developed in Hamelin in 2023. The project was brought to the Hessian state capital by City Management Wiesbaden and the Environmental and Parks Department. The planting was designed and implemented free of charge by the Wiesbaden Cemetery Gardeners' Association. They are also responsible for the maintenance and preservation of the plant diversity. It is supported by the Hesse-Thuringia Trust Agency for Permanent Grave Care and the Baden-Württemberg-Hesse Horticultural Association.

The project is funded as part of the Federal Ministry of Housing, Urban Development and Building's "Sustainable inner cities and centers" (ZIZ) programme. The aim is to provide new impetus for vibrant city centers with innovative, temporary measures.
