In one of the largest botanical gardens in the world, around 22,000 different types of plants grow across 106 acres, drawing its inspiration from 19th-century garden design. The 82-foot-high Tropical Greenhouse, built in an iconic Art Nouveau style, is the centerpiece of the gardens, where visitors can often enjoy classical concerts amongst an array of tropical and subtropical flora. The adjacent museum is one of the few in Central Europe, perfectly complementing the gardens.
