Landesgartenschau is an public horticultural show of German and Austrian federal states . Through it quality of life and the ecological climate in the cities are improved. Frequently the horticultural shows serve urban and regional policy development objectives.Therefore horticultural shows are often not placed in particularly beautiful landscapes, but on the contrary rather in such districts, which have a particular disadvantage (e.g. by mining damage), where they act structure promoting and helping to realize urban planning objectives. The investments that are made in the context of the LGS, help each district to larger and usually also lasting appeal. In addition, State Horticultural Shows are now also measures of city marketing, as they also can increase the awareness of a city than a half-year-long big event.
