The art nouveau mansion designed by Antoni Gaudi was officially re-inaugurated after a 7-year renovation costing 9 million euros. Palau Guell was built between 1886 and 1890 for textile mogul Eusebi Guell, Guadi's life-long patron who lived in the mansion with his family for 20 years. Photo courtesy: AFP
