The Vienna Botanical Garden covers 8 hectares and is directly adjacent to the Belvedere Gardens. Currently, there are over 11,500 plant species growing here, including tropical plants such as orchids, bromelia, cruet and marzate family. The botanical garden is part of the University of Vienna, only the tropical part located in the center of the complex is open to visitors.
The gardens date back to 1754, when the Empress Maria Teresa founded Hortus Botanicus Vindobonensis with the renowned botanist Nikolause von Jacquin. Greenhouses with an area of approximately 1500 m² were built only at the end of the 19th century. A few years later, the Institute of Botany was opened. At the end of World War II, the Institute building, all greenhouses and the entire garden were bombed and severely damaged. They were rebuilt and gradually expanded only in the years 1970-1995.
