"This romantically named mural near the Catedral de Barcelona was only meant to be a temporary exhibition. It was unveiled in 2014 for the 300th anniversary of September 11, 1714, a day known as Catalonia Day, or La Diada, which commemorates Catalan surrender in the War of Spanish Succession. The day is a tribute to the Catalan lives lost, to regional identity, and to freedom. The mural is made up of 4,000 tiles with photos printed onto them arranged into mosaics by color and density so that, from afar, the 26-foot-tall mural shows two people kissing. This kiss—a symbol of affection, empathy, and liberty—felt so poignant that the local government never took it down." - Gemma Askham
