Tranquility and relaxation are the bywords on any stroll through Adelaide's Botanic Garden. The garden provides a great opportunity to relax amidst subtropical plants or to wine and dine next to the lake. Two of the most impressive glasshouse structures in the garden are literally an age apart. The elegant Palm House, which opened in 1877, is recognized as the finest Victorian glasshouse in Australia and houses a fascinating display of Madagascan flora. Conversely, the space-age Bicentennial Conservatory encloses tropical rain forest plants from northern Australia, the Pacific islands and Asia.
