The Diego Rivera Mural Museum is dedicated to a single fresco - but what a one! The mural "Sunday Dream in Alameda Park" was painted by Rivera on the wall of the Prado Hotel for a year and was completed in 1947. The fresco depicts the events of the history of Mexico from the colonial era and the Inquisition, to the middle of the twentieth century, interspersed with memories from the artist's childhood. Diego Rivera portrayed himself as a child standing in front of his second wife Frida Kahlo. As a result of damage from the 1985 earthquake, the Prado Hotel was due to be demolished. To save the unique fresco, a piece of wall with a fresco, weighing 15 tons, in a metal frame, was transported to the Alameda Park area, where the museum building was built. For ease of transportation, the fresco was shortened by 60 cm in length and 70 cm in height and now has a length of 15 meters and a width of 4 meters. After cleaning the surface of the fresco, repairing the cracks and applying special protection, the fresco museum was opened to the public in 1988.
