Paseo del Prado and >Buen Retiro, a landscape of Arts and Sciences. The Paseo del Prado is one of the main boulevards in Madrid, Spain. It runs north–south between the Plaza de Cibeles and the Plaza del Emperador Carlos V (also known as Plaza de Atocha), with the Plaza de Cánovas del Castillo (the location of the Fuente de Neptuno, and of the Ritz and Palace five-star hotels) lying approximately in the middle. The Paseo del Prado forms the southern end of the city's central axis (which continues to the north of Cibeles as the Paseo de Recoletos, and further north as the Paseo de la Castellana). It enjoys the status of Bien de Interés Cultural (BIC), and as part of a combined UNESCO World Heritage Site with Buen Retiro Park since 2020.
