The Botanic Gardens of Barcelona, originally established in 1930, were completely overhauled in the 1990s. They are now a beautifully landscaped, green space that showcases Mediterranean-climate plants from all over the globe, including Africa, Australia, California, the Canary Islands, and Chile. The collection continues to evolve. New species are grown in greenhouses every year and planted in the gardens. Those that fail to flourish in Montjuïc’s climate and soils are pruned from the collection. The 71 planting zones are connected by walking paths, many of them crossing small bridges and walkways over ponds.
