The Federal Garden Show 2019 (BUGA 2019) took place from April 17 to October 6, 2019 in Heilbronn in Baden-Württemberg. On about 40 hectares between the old arm of the Neckar River and the Neckar Canal, an approximately three-hectare city exhibition with 23 architecturally innovative buildings was presented in addition to the garden exhibition. More than 2.3 million people visited the show [1]. After the end of the Federal Horticultural Show, the site is to be further developed into Heilbronn's new "urban quarter" Neckarbogen with around 3,500 residents. The first buildings of the green and family-friendly planned quarter have already received several awards. (Source: Wikipedia)
