Modern use of historical architectural objects of Botanical gardening (foreign experience)

Studying the experience of European countries that have influenced the development of world botanical architecture, such as Italy, France, Belgium, Austria and Germany, in the field of restoration and use of these historical structures, can serve as a basis for choosing alternative ways of functional use of historical greenhouses in St. Petersburg.
