in 1925 French landscape architect Jean-Claude Nicolas Forestier redesigned the Paseo del Prado, lined it with trees, bronze sculptures of lions, coral stone walls and marble benches.

They were authored by French sculptor Jean Puiforcat and Cuban-born master caster Juan Comas Masique, who used the metal from decommissioned cannons to forge the lions.

At the corner of Cárcel street the car dealership Packard & Cunnigham was located, and in 1940 the radio network RHC-Cadena Azul established its studios on the Prado.

The Congrès internationaux d'architecture moderne (CIAM), was an organization founded in 1928 and disbanded in 1959, responsible for a series of events and congresses arranged across Europe by the most prominent architects of the time, with the objective of spreading the principles of the Modern Movement focusing in all the main domains of architecture, landscape architecture, urbanism, industrial design, and many other design practices.

The Paseo del Prado had been a replacement for the first promenade in the City of La Alameda de Paula which was built around 1776 by Antonio Fernández Trevejo.
