The Domus Aurea was the urban villa that Emperor Nero built after the devastating fire in A.D. 64 It destroyed much of the center of Rome. The destruction of a good part of the city center allowed the emperor to expropriate an area of about 80 hectares and build a mansion that stretched between the Palatine, Esquiline and Celio. For its beauty and wealth became known as the Domus Aurea. The villa consisted of a series of buildings separated by gardens, woods and vineyards and an artificial lake, located in the valley where today stands the Colosseum. The main sections of the building were on the Palatine and the Opium Hill and were renowned for their lavish decor, where stucco, paint and colored marbles were added coatings in gold and precious stones. The parties visited today are on the Colle Oppio: environments probably intended for parties and banquets that were buried remained unknown until the Renaissance. Only then, after a few incidental findings, passionate artists of antiquity as Pinturicchio, Ghirlandaio, Raphael and Giulio Romano began to descend from above in those "underground caves", to copy the motifs that they kept and that, precisely where they are located, They became known as "grotesque".
