In Park Ciutadella you'll find an attraction that's not as crowded as the rest of the park can sometimes be. The Umbracle, a modernist building designed by Josep Fontserè and built by Josep Amargós between 1883 and 1887, features five arches built with steel beams and brick pillars covering it. The roof is made of wood and lets some light in, re-creating the lighting of a rainforest. These conditions allow for a type of greenhouse, where plant species originating from 20 different countries have been be planted and grow in rows under the arches. Take a moment to stroll round the lush nature.
