The tour begins at the Museo Nacional del Prado, one of the most important paintings in the world and an essential reference for understanding the evolution of European art between the 16th and 19th centuries. During this first part, the visitor delves into the history of the Spanish monarchy and its role as a great patron, which allowed to assemble an exceptional collection based on the personal taste of kings and queens. The visit is structured around a carefully chosen selection of masterpieces that allow you to interpret the great moments of Western art. Iconic paintings such as Las Meninas de Velázquez, key to understanding modern painting, the enigmatic atmospheres of El Bosco, and the emotional intensity of Goya, whose work marks the transition to the contemporary world, are analysed. Rather than a chronological tour, a narrative reading is proposed that connects art, power, religion and society.
